I had an appointment through one of the big agencies a few years back that I walked out on. Very ugly in the face, but you can't tell that from the photos. Body might have been a match, so not exactly bait and switch. Apartment was a bit messy. Her fake lashes were all off-kilter.
I was in the bathroom for about 10 minutes deciding what I was going to do, then summoned up my courage and told her, gave her half and left. She had no issues with it. Come to think of it, maybe she didn't want to work.
I texted the booker back, explained my disappointment and that I left and gave half. I was worried at the time they might expect a full share from her. The booker ws fine with it. If most guys are leaving $20, maybe I just left too much.
