Completely random question, but...
What is the expectation when someone is finished with their food at a fast food place like McDonalds, etc?
So I've noticed the few times we've been to fast food places around town--McDonalds, Burger King, KFC and the like--that people leave their trash behind on tables. The tables are then either cleared by customers eager to claim the table for themselves, or eventually by an employee.
The few times I threw away my own trash and cleared my tray I got a very surprised "Ohh?, Uh, thank you" from the attendant. Am I not supposed to be doing that? It would drive me nuts to leave my trash behind, especially when rubbish bins seem to be plentiful and the effort to do so would take a few seconds. And it honestly never occurred to me to leave it behind.
