It works both ways. I was a waiter at Marie Calendar's all through college.
It wasn't the most sophisticated crowd. We served a fairly mediocre turkey pot pie that couldn't be kept overnight, so we planned to run out. For some reason customers loved it and those in the know would ask us to save one right away, but sometimes we were out way too early. I remember one large party who all wanted pot pies. I told them I was sorry and that we were out but the very bossy matriarch said, "Don't listen to him he's kidding!" I assured her I never kid about pot pies and apologized again and as the others at the table started choosing alternatives she kept insisting, "No, he's KIDDING! Stop it! They can't be out of that many pot pies." It went on for what seemed like hours.
The sandwiches were called "stacks," as in, "Tuna Stack," "Ham Stack," etc. One customer asked the waitress "how many hotcakes come with that tuna stack."
My little sister was a hostess and she had a party of 8 waiting for a large table to clear. Meanwhile a two-top cleared and she sat the next party of two. A woman from the party of 8 stormed up to her and demanded to know why those two were seated before her when they had come in afterwards. My sister tried to explain that her party would not have fit at the small table that was available but the lady stormed off, went back to her party, pointed at my sis theatrically and shouted, "SHE didn't even apologize!"
Ah, memories.
