Keith and Rich were hot for Barb and Denise. One of them had been promised a hookup with Barb.
Men don't like other men horning in, believe me.
So, Rich had access to drugs. Ever heard of GMBH, RUFFY'S ??????
I have had friends who had someone put that in their drinks. One woman went to the bathroom,and came out later with her underpants down to her knees and just sat down at the table, completely oblivious.
She had to be put in a car and driven home.
Another barely made it home. He got inside his door and set down on the floor for the next 4 hours.
The woman was spiked because someone wanted to get her in their car and have their way, the guy was spiked, because he was in the way.
