"Can I have two of those buffalo mozzarellas, please?"
"Have you got a number?"
"Have I got a what?"
"A number."
"What sort of number?"
"A number from that roll over there, to show it's your turn to be served."
"I'm the only person here."
"It's just some of the other customers might get upset if I serve you and you haven't got a number and they have."
"There aren't any other customers."
"I know, but if some came along…"
"Well, they'd just have to wait because I was here first, wouldn't they?"
"…Mozzarella, was it?"
