The man in the gray suit has been watching the fun at a distance, with some amusement. Not much, though: he knows that A random act of Fucking Milliways removes patrons' memories,
with hilarious consequences is the sort of thing that, anywhere else, would end (in the words of a great American poet) with somebody going to emergency and somebody going to jail.
Besides, he can't really afford to get caught up in it. He's got places to be. Right now, he's only here to get to the
party. He's botherable until then, I guess, but he may leave at any moment.
