I expect to be waited on in a restaurant/Cafe, or gun store. The grocery store (before self-check), I, like everyone else, would look for the "shortest checkout line".
With self-checkout, I get my stuff, scan the bar codes, stick my credit card in the slot, and get the hell outta there.
I like folks that insist on being checked out. While they're standing in line, I'm leaving with my stuff, and they didn't hold me up.
If you like standing in line, I think that's great. Makes my entry, and exit much quicker, and I don't have to stand in the middle of all that coughing, and wheezing.
