Just in case anyone was curious (especially since I find this a little sad) here is the breakdown to the $140 pp for his friends bachelor party:
$25 per open bar (there are 2)
$40 for dinner
$50 for strippers
FI is a little curious where these strippers are going to be (its a fairly big bar and I can't imagine bars would allow this).
FI doesn't really know whether he has to pay for the strippers if he is only attending the first open bar and dinner. So if anyone has any ideas about that, let me know.
