Well, my favorite customers are the ones who are shocked to find that the mac & cheese, baked beans and baked potatoes are all cold, even though they are kept in the salad case. I also like the ones who complain that it's cheaper to buy the container of potato and macaroni salad out of the case in front, than to have me scoop it out and weigh it. They have to pay my wages somehow!
Also the ones who ask for a chicken breast, and when I move a thigh out of the way to get to it, they say they'll take that piece...the THIGH. Then they argue with me over whether or not it is a thigh. And then there are the ones who complain that I don't have a register, even though Starbucks is about 15 feet away. But perhaps my favorites are the ones who come to me with produce issues, when they usually have to walk past the produce person to get to me. Oh, and the many people who come and ask where stuff is in the rest of the store, as if I have time to find out where tortillas are and commit it to memory. That's what grocery managers are for.
I'll stop now, but I could type forever. I love retail.
