Seriously, what's worse than a classless douche asking how much your car costs? The classless douche who says, "if you have to ask how much it costs, you can't afford it".
It takes a special kind of person to put someone down because they can't afford the same shit you can. I just don't understand the motivation to use a situation where you could be humble and kind, to rather be a complete jackass. And THEN, complain about the person you were a jackass to.
If you want people to stop being classless, maybe you stop acting classless.
