Is the client compensating for canceling a rare occurrence? I had to cancel an appointment recently due to an unexpected (and unwelcomed) change in my schedule. The few times over many years that this has happened I always insist on sending the escort something, usually $100 or so. I've never thought about sending the entire fee, but I feel that sending something is appropriate. Easier now with Venmo, PayPal, etc., but back in the day I thought nothing of slipping a few bills or a check in the mail. Is this not common?
