Tried to book him last Sunday but he didn't have 90 mins available as he had 5 guys right before me so could only do an hour. I said we can do another weekend as I prefer the longer sessions, he launched into me and became rude, saying forget trying to book a session. We talked and he apologized for jumping to the conclusion that I was assuming his review on his profile was accurate/that's why I asked for another date. We rescheduled for yesterday.
A few times during the week confirmed we were still OK. 40 minutes before we were supposed to meet he texted with this long story about how he was busy with work and only wanted to do 60 minutes instead of 90, but would make 90 work if I wanted that. Said I preferred 90 as he knew and he said understood, but went silent. 15 mins before we were supposed to meet, I asked what was up and he said he can't do 90 minute sessions anymore and to have a good weekend. It was a joke to him that he had to cancel. Incredibly unprofessional.
This guy clearly likes the game of scheduling and cancelling last minute because of "work". As @dctraveler said - beware.
