I used to go to a massage shop quite often, and always just gave 100 bucks for part 3.

One day the mamasan pulled me aside and whispered to me that: “You are giving them too much, most will settle with 60-70”.

I ignored her advice, as I felt the ladies there were generally all very nice and (maybe because I tipped well) gave good services.

After a few months I stopped going, as most of the good girls left. I was told by the remaining few that they were considering leaving, too, because the mamasan is pressuring them to accept FS for close to nothing.
