I never said "I'll pay you later". I told her to cancel the session, she insisted I come along and pay her later because I will be charged half the fee for the room she rents out.

To clarify, I spent the money and then emailed the T to tell her to cancel because the money had been spent. She wanted me to come along, so I agreed and said I will pay you the full money the next session. If she'd have said, "OK skip this session" I'd have been happy about that. I would never go to a session with no money and say "I'll pay you later". That would just be plain rude.

Sometimes I wonder if people actually read my threads correctly.
