Vivienne is an escort.
Description

He already done pick out Vivienne. She was older than the others, but she kept her bits tight, and she was nice as buttered toast. She do play with Thumper’s dingdong all night long. That bitch makes her own sushi, she ain’t even oriental. She’s just fancy. Got a Japanese knife and everything. That’s the kinda bitch Thumper wanna spend a night with. He could avoid pitching purple at Miriam if he got the bliss of pinkness with Vivienne.

Vivienne went to the bar. She liked Max and fully intended to go back out there to talk to him, Davon be damned, but not until Haykh had come and gone. He was her pimp.
Well, he was the pimp at Lipsweet, which was where Vivienne met her clients. She would not call him her pimp. He was just the pimp at the place where she worked now. But that was not a distinction she would make afront him.
Teddy, the bartender who made her vodka-tonic, wasn’t her bartender after all. He just bartended at the place where she was. Haykh pimped at the place where she was. Maybe in some glorious Star Trekian future we’ll have auto-dispensed drinks and robotic pimps to extract money from deadbeats.
But Vivienne liked talking to Teddy, so fuck it, screw the robots.
From Max the Beach Bum
Vivienne was a older lady, wise as a turtle but twice as sexy. Thumper ain’t cheating on Jamella, but it ain’t cheating to mack, and Vivienne was sweet like skittles in syrup, and she got things to say — that female been to Japan! She pretty as a cherry tree, and she got a throaty voice like she been sucking off cheese graters. Thumper like to mack on her, even if they ain’t fucking. She was very mackable.
