Junior, it's sad and disappointing that this has happened to you. As this is the first time anything like it has happened in over a year of escorting, the incident is about this client, not about your business model. I won't say move on, because even one such incident can leave a bad taste in your mouth. As Smurof suggested, the client may not have realised that he shorted you, but that's likely giving him too much credit (and he did screw you around in the lead-up to the meeting). All that, and the fact that the meeting seemed like hard work, seems to be telling you he's not a client you would want to repeat. Accentuate the positive!
