I think it's only acceptable as a joke, and for so many people it's definitely not a joke. It's some serious role play.
There's really no supreme logic to why I hate it. I just think it's immature and not necessary. But I don't complain about it at all because I realize that it actually is a part of the game for some people. I do always avoid the burger refuge and the area where it happens, though. Out of sight, out of mind.
