I don’t want to rip you apart but :
1) No. What guy wants to send money to an SP they’ve never met and reveal their identity in the process with so many e-transfer scams out there. Stupid.
2) How does an e-mail address and booking eliminate no-shows? It doesn’t. Give your head a shake.
3) Funny how your definition of booking anything less than an hour is in your determination being a cheap skate. Not all guys are 3 shots in an hour kind of guys. Not everyone wants or needs to cuddle afterwards. Some guys just want to test the waters and see if a women is to their liking in a half hour without wasting cold hard cash booking an hour only to find out there’s zero chemistry. It’s called being prudent, and there is no correlation between that and being a time waster. None whatsoever.
