The problem Axel, with anything you say is that especially if it happened more than...a week ago, and especially if it happened "years ago" there is an almost certain chance that you are remembering the details wrong. Plus, you might not have been close enough to whatever was happening to even have known exactly what was happening in the first place.
Basically, I haven't seen you recall a single event from the past entirely accurately.
This guy could have been an actual host. He could have been someone who played himself. He could have been someone who brought in friends. The promo chips might have been given to him to distribute. The promo chips might have been handed directly to the players.
Almost nothing you recollect turns out to be exactly the way it happened.
Plus if it was during your clubbing days you know you were drinking heavily during that time.
Let's just say that maybe things happened the way you recollect, and maybe not.
