[Oof, it looks like Yusuke was getting really uncomfortable. He'll make a note not to do something like that again.]

Not if it's advertised as a special area that's just named something like " Le Grinder " that just has nicer furniture and is a room for a group to hold a party. It's more of a joke in that case? If I was saying it leads to a bed then leads to a room, then they would get rightfully angry.
