Who said anything about bad service? No one. If you get bad service, don't tip - don't go back. What I said is that he was willing to do more for those who tip consistently. It only makes sense, if you have a choice between two clients wanting the same appointment time, I think everyone would choose the one who tips regularly. If a client asks for a prostate massage but never tips, why bother? But if they tip regularly the odds will go way up that the masseur says "Sure." Do you need to tip masseurs who run their own business? I guess not, but I appreciate good service and will gladly pay a few extra bucks to ensure it. I think it is reasonable to expect a good massage when you don't tip, but I also think it is reasonable to expect better service when I do tip regularly.
