The therapist that massaged me was actually amazing, but I was so pissed off I could barely enjoy it. I was in Vegas from out of town and saw a good deal on Groupon so I purchased it. When I arrived a little early, they told me that I needed to pay for the tip up front. I said I'd rather not. She told me I had to according to her manager and the minimum tip was $15 for a 90 minute. We went back and forth for a bit about that being their policy and me saying why that was not customary and unprofessional in my opinion. Having a massage license myself in California, it was really upsetting having this debate with another therapist. I happen to peek at the table and I noticed the license they were displaying was expired by a couple of weeks, so I asked the girl was it also their policy to display expired licenses? Of course she said it was ok bc it's just a little expired, but at that point the conversation was over and she told me someone would see me shortly. Of course they made me wait to my scheduled time, despite a walk-in customer who came after me, being escorted to a room right away. I guess he tipped upfront. Nevertheless... I received my massage and gave them exactly $15 but not before letting them know that I usually tip $20 for a 90 minute and that they completely ruined my zen with this bs. Sadly, I won't be going there again.
