I make $30 an hour after tax, so I value the fruit of my labour. Every time I spend any money, I have to think if I'm getting screwed. With inflation so high and a lot less disposable income, cannot afford to be wasteful, which means I'm also not a sucker that makes another trip to buy a gift.
I tipped when I was a few years younger, but my attitude had since changed, these days I won't throw away even $20. I mostly book one hour sessions and if I like the lady, I book more sessions. Of course ladies like generous clients, I like it when people give me free money too. It's human nature.
These are the scenarios you can waste money when you tip:
1. You don't want to see the lady again, which is like 90% of the time for me. I don't build rapport.
2. The lady quits the industry soon after the session, which happens to a lot of young hotties I want to see again.
3. The lady won't offer you a particular service even after giving generous tips. I once tipped this hot girl $80 on top of a $300 session, and she won't even let me do her doggystyle because she's not comfortable with it.
