Why do players think they can do this when not in a hand?

I get this at least a few times a week:

NL holdem ring games, a player will push all in, and another player WITHOUT cards will ask how much that is. I always say, sorry, you don't have cards. Then they get all pissy that they think they are mystically entitled to slow down the game to get a chip count when they have ZERO PENDING ACTION in the hand! Man, these F'in learned fom the WPT morons are really getting ridiculous. They all think they know every single rule and yet have zero clue.
