Speaking from experience, the pizza delivery thing is weirdly plausible. I was propositioned twice while delivering Pizza, once by a very drunk lady who really wanted someone to take her to a particular club (about twenty minutes away) the other time by a guy who really wasn't my type, but apparently I was REALLY his. I politely declined on both occasions as besides the relative sobriety levels being a dealbreaker my girlfriend wouldn't have appreciated me taking up the first offer and I wouldn't have appreciated the second.
Plus another driver I worked with got invited in for some hanky panky at a remote house. The scantily clad woman rubbed up against him and stripped his clothes off, while her partner in crime stole all the cash he had on him. They then followed up by snapping a Polaroid and threatening to send it to the store if he told anyone. Obviously he didn't let that stop him and they never sent I'm the photo. Early stages of Meth abuse seem like fun.

Oh yeah, which one gets you going?
The substance affected bleach blonde answering the door in a towel then trying to entice the guy a couple of years younger than her with some transactional sex?
Chunky "straight" bear trying to get some strange off the straight & unimaginative delivery driver while his wife is out of the house?
Or the attempted blackmail after sexual misadventure with a meth-head?
I mean I can see all of those scenarios cropping up in different porn films, I'm not trying to yuck anyone's yum here.
