I can't speak for ThatGuy nor the club but I think the hat person would have to be more concerned about those standing behind them. Even if some frutstrated patron ended up getting kicked out, the hat might not make it out in the same condition that it came in.
On a personal level, I think it's rude to wear big view obstructing hats into places like theatres and concert venues. Or, at least, keeping them on during a performance. Kind of like those boars who keep their cell phones on loud rings and/or hold private conversations as though they are meant to be shared with everyone in the room. Just my opinion.
The one exception about wearing the hat all night would be if that person stayed in the very last row or way in the back so to guarantee that no one would have to suffer from neck wrench.
