Somewhat related experience a few weeks ago - I saw one of my favorites that I hadn’t seen in about a year due to various scheduling issues on both of our ends. I was used to paying a certain amount for a 60 minute session with him, but after the massage he said his price was $100 more than what I previously paid. I mentioned that he hadn’t said anything about that when we booked and that it’s not reflected on his ad (it used to list his rate but now says “ask me”). It was a good massage so I paid the inflated rate but no tip and I’ve got no plans to see him again in the future
