I did my time in a Subway and a couple KFCs, the amount of people who think asking for a Big Mac is the funniest thing...

I waited tables for the briefest moment and had a similar experience with customers asking for "a million dollars". They thought it was soo witty in response to "Is there anything else I can get for you?"

Sometimes it took everything in me to not roll my eyes at them lol
