You think he'd deposit his victims further away
I couldn't tell if he treated all his "victims" the same way but why leave John right outside his place in the alley?
Might John not come back once he realized he'd been had and do something violent to the host guy (LOL. I just watched this and I can't remember the character's first name and I don't feel like looking back at the credit).
Anyway, my point is he could have driven John way far away and ditched him while he was still under the influence and with no cell phone or car or money John probably wouldn't have been able to get back too quickly (assuming he could find the place again)
