I placed my order at White Castle and paid. About a minute later the counter girl came back and said “May I take your order?” Thinking someone was behind me, I stepped to the side. The counter girl was still looking at me. I looked over my shoulder. Not only was no one behind me, but I was the only customer in the place.
Whenever my kids get upset about some stupidity at the counter of a store, I tell them to be patient and understanding. There is a REASON this person is working behind the counter at the fast-food joint or department store at minimum wage. Trying to teach them some compassion, and also an example of “don’t grow up to be one of these”.
OTOH, other than new trainees, I don’t recall a single “bad/idiot” person behind the checkout counter of our local Safeway grocery store.
