I worked for two years in a Wal-Mart Seafood Dept. I was there six months before they found out I don't eat the stuff.

Every once in a while, some woman would come up to the counter, and the conversation would go something like this:

"Do you have crabs?"

Me: (keeping my Customer Service Face on) "Ma'am, Wal-Mart is proud to sell King Crab Legs, Snow Crab Legs, Whole Dungeness Crab, and Imitation Crab Meat! Would any of that interest you?"

(A slightly annoyed look, and a snicker from her or her companions) "I didn't ask you THAT! I asked if you have crabs!"

I was not paid enough to be nice to these people.
