That is pretty screwed up, I have been to Nina's garage and its quite well setup looks like a mini bordello with posters of Marilyn Monroe and mini white lights in a pink painted room and lace curtains, this was years ago. Nina is older for sure and her vibe is get the job done but she needs that money. To have a guy on the hook for $1800 would be a huge score for her as her rates were on the low end of the scale but appropriate for what you got.
The poor guy had this vision of a glorious hot encounter in his head with two hotties and was prepared to pay an arm and a leg for it.
Nina really fucked up she should have just asked him for a reasonable cancellation fee and made every attempt to help him out of there. She too got caught up with her fantasy vision of a big pay date and went all out to collect it, not cool. Lucky for him he knew who to call and his sister was there to help get him out. This would have been a real shit show had the money transfer gone through and he would have been in the middle of a druggie party. The other girl OD'g and dying is just nuts that should have been reason enough to help get him out of there. Goes to show do your research things are never what they seem, he is very lucky to get out reasonably unscathed, good for him going to court hopefully Nina is closed down for good.
