Tim: so sorry that happened to you at the Spa. It should never have happened and I join the others in encouraging you to report the masseur who demanded a bigger tip and then did a sub-par massage. That happened to me once at a Spa in NYC but it wasn’t on the table, but afterward went to the front desk to check out. The masseur said I was to pay a $30 minimum tip, for a 90min session. I asked him why since I had him before and he never said anything about the amount of my tip. We hashed it out then and there. I was more disappointed than anything else. I know these guys are trying to make a living but they won’t make as much as they could if they do not great their customers right.
