Number One. It's okay for the boss to talk your ear off, but you aren't allowed to talk to anyone else in the office without "the look" and in some cases "The clear the throat" get back to work bs.
Number Two. "Oh just one more thing..." why is one more thing just before 5 p.m.
Number Three. Someone always needs the boss when he or she is still out for lunch. Two freakin' hours and they are still out to lunch!
