Of course if the players who attended the party didn't know there would be alcohol and strippers and left as soon as they discovered that, then they have nothing to be ashamed of. However, I don't think that is the case here. I could be wrong.
It's not clear they knew about the strippers beforehand.
One of the players who lived at the house went to his room and was watching Letterman.
The Selligman boy left soon after the girl arrived and the other boy supposedly was at a Mexican restaurant. It's not clear he was there at all.
and we don't even know who they are--yet they are all paying a horrible price for hiring strippers, which isn't even illegal.
