"You know that coffee you ordered? It's actually decaf even though you asked for regular. We'd rather you sit back, relax and fall asleep so you don't bother us too much," one flight attendant said.
"If a flight is going to be late anyway, we've been known to delay it even further to make sure our overtime pay kicks in," another said.
"Who do we upgrade? Not the slob who's dressed in a dirty tank top. It helps if you're extremely nice, well dressed, pregnant, very tall, good looking, one of our friends or all of the above," one of the attendants revealed.
"I want to yank your headphones off after I've asked you what you want to drink and you've responded "huh?" three times. After the fourth, I just move on or give you Coke," a flight attendant said.
