Just about every time I check out anywhere:

"Your doctor must hate you, how high is your cholesterol?"

I usually say "Great now that I'm not eating grains any more."

On two separate occasions, I got: "Holy Bacon, Batman!"

I bought beef kidneys and the cashier, as she was sliding it across the scanner, realized what it was and just about threw it as if it had a roach/mouse/other-disgusting-critter on it. Both her and the bagger were like, "I didn't know we had this. You EAT this??"

I've also had cashiers ask if [various food, usually veggie] is any good.

A big one is, "How do you cook this?" I have to restrain myself on this one as cooking really does excite me and I'll give them every last detail before I realize what's happening, lol. 8)

Cashier, looking at lots of meat- "Having a party?"

Me, after much consideration- "... Yes!"

Seeing most of the time what I buy has no barcode, I get a lot of "What is this?" as the cashier searches for the code to punch in the register. Usually I answer with, um that's a pepper. IT's amazing how disconnect people are to non-scanable food.

Interesting that you've mentioned this. When I go to the market and check out, I get funny looks about all the different vegetables I get. Also how most of the cashiers don't know what most of these vegetables are, I've worked in the Food service industry for years, so maybe that's my heads up on what a rutabaga is,parsnips,beets,plantains etc.. It's like I have a cart full of garbage to them or something. I also find it kind of sad that most people don't know what 'Food" is, not trying to come off pretentious or snobby, just a genuine concern for our bodies and health..just a thought

In the summertime it's always "having a barbecue?" since I am buying 10 or so steaks and a couple of roasts. I love smiling and saying "nope, just a weeks worth of beef for myself"

actually i've had great responses from my cart, generally being "I want to eat at YOUR house!" (or a version of that). Usually my cart has: assorted meats, lots of veggies, kerrygold butter, bottled (yes, in a glass bottle) heavy creme and assorted fruits. If someone asks, i'll tell 'em how we eat...lots of delicious fats, meats, veggies and fruits. no grains. (with an occasional lapse into a pain de george organic loaf of bread with bone marrow, tomato and raw onion...oh geeze..it's a glutenous splurge but mighty fine). What i'm shocked at is the carts of crap other people with children are pulling around and I have to literally shut my yap to not say anything....not in a mean way, but just want to SAY something...that used to be MY cart...and I THOUGHT I was feeding my children well. It's hard not to, but just like religion, unless you're INVITED to discuss it, you just DON'T do it.

Actually had a curious Trader Joe's cashier go paleo after asking how I was "able to even walk to the grocery store" with a cart full of Kerrygold, uncured bacon, and grass-fed beef (I was even in my Vibrams which I'm sure did something to add to the effect). Instantly curious and asked a few questions. Directed her towards MDA (my personal favorite to recommend - the other ones come after - but I find MDA is the least "scary" for newbies - the other guys come once they report back to me as a believer about the easy wakeup, the insane amounts of energy, the seemingly superhuman strength, etc...) and saw her a few weeks later, looking several pounds lighter and psyched to report back that she was following the diet. Nothing quite like paying it forward with this!

A very old man in a wheelchair in front of me picked up my jar of pickled herring. His caretaker smacked it out of his hand with a "tsk, tsk. That's not yours." To which he replied, "But that's the GOOD STUFF! Why can't we every get that?"

I've gotten the standard "You eat healthy" or "That's a lot of meat" or "Murder an animal much?" The last one from another customer. I imagine she was a vegan or something.

The best I got was not paleo related: I used to work in engineering at UPS, and at the time I was head of our hazmat response teams. We ran out of clay absorbent so I ran down to Wal-Mart to get some cat litter to tide us over until we could get some more absorbent in. I grabbed 300 lbs of cat litter and headed for the checkout. As I wheeled up to the register the cashier asked me, "What on earth could you possibly need that much litter for?" I looked her in the eyes and replied "I love cats. So much."

I can usually tell when the cashier or customers behind me are vegan, based on their looks of horror as I set down a couple chops from a cute, innocent lamb.

If you want to see the cashier's eyes really pop out of their head, you should try shopping for a Raw Fed dog!

None that I can think of, but I try to buy all our meat and eggs from a local farmer or at our local deli and butcher.

Just two days ago I had a cute girl bagger at Whole Foods ask me "So are you going to compare those different kinds of sardines and see which you like better?" To which I responded "Yeah I'm going to write up a full report, I can give you a copy if you are interested" with a smirk. She then smiled and flicked her hair. I should have asked for her contact info, but she seemed like she might be a bit young for me... I'm still trying to calibrate for that (my first time being single in quite a long time).

I get the feeling that the people with the junk-loaded carts are judging me as much as I am judging them. Some of the looks on their faces are priceless. As far as the cashiers, I agree that I have probably identified vegetables for them more times than I can count.

Are those bones for your dog? Me: No way! They're allllll mine.

Most of the comments I hear in the grocery store are from my three year old as we go through the aisles and pass other peoples' carts.... "Cheetos!" "Coke!" Cookies!" "Mommy can we get those?" To which I usually reply within earshot of others buying said items- "No baby that's not good for us. We don't buy that stuff remember?" Of course this usually leads to scrutiny of my cart. You can just see them feeling sorry for my poor sugar deprived child just as I am feeling sorry for their vegetable and meat deprived kids :)

Thankfully my child is a very good eater. But grocery stores are full of temptation!

We've been asked if we run a restaurant, due to the quantity of eggs and veggies.

The Asian food store people get very confused about what us white people could possibly be using so much coconut milk for.

The other day, I bought 10 packages of Kerrygold butter and 6 bottles of heavy cream at Trader Joe's, and when asked what I was going to do with all this, I told the cashier, "simple, I'm going to eat the butter and drink the cream." Wish I had a camera to capture the look on their faces. Gotta love it.

"Does this actually taste good??"

(referring to veggies and periodically fish...sigh...)

One of the best ones I remember was buying Coconut oil and cashier asked my what I use it for and I replied "everything"

Then went into detail on how I use it sometimes to make a stir fry with just veggies and meat, with coconut oil.

To hear the reply " oh your young and can still get away with eating that way, I love the taste but I need to watch my weight"

I bit my lip, looked at my girlfriend paid and walked away... it was very close to being an hour long debate...

"That's a lot of meat."

I once checked out with 4 pounds of butter (hey, they were on sale) a couple pounds of bacon, a pound of ground lamb, some heavy whipping cream, goat cheese, a couple dozen eggs and a boat load of produce. The checkout guy says: "You must not eat any sugar. No wonder you're so thin."

I still think my favorite was when I was buying lard and the bagger asked me what I was going to do with it. When I told him I was going to eat it he asked "Is that SAFE?!?!"

ETA: I should mention it was not the shelf stable block 'o lard. It was a big bag of pork fat that I was going to render.

But mostly I just get questions about the number of coupons I use.

1991, I was a university student and by some fluke, everything in my basket was healthy-looking stuff like bell peppers. The cashier said something along the lines of, "Ooh! That all looks very healthy." I just smiled. She couldn't have known I was going to wash it all down with an ungodly amount of cheap beer that I'd bought earlier that day.

We buy 4-6 dozen eggs at a time (myself, wife, and two paleo kid-lets like our eggs). By far it's always the standout item in the cart to the cashier.

My wife usually tells the cashier, "oh, my husband is training and eats a lot of eggs."

Having a cook out?

Nope. I just like beef.

"What do you do with all those potatoes?"

"Meat n' Potatos, eh?"
