STOP WHINING. Yes, I know you are run down. You have already told me 14 times today. I am also run down and so is everyone else who works here. The chef, for example, worked 13-hour shifts every day for 28 days in a row - yet he has never told me that he is feeling "run down."
But well done: your constant passive-aggressive pissing and moaning ensured that the head waitress sent you home early today, just so that we wouldn't have to listen to your complaining any more.
