Tomorrow I will be seeing a client of mine who forgot his Tuesday appt. (even after I confirmed it, leaving a message on his home voice mail). I called him 15 minutes after he was due in and he just said that he forgot, sounded apologetic and inferred he didn't get my message.I plan on telling him that he is expected to pay for that missed appointment, but should I tell him before or after tomorrow's appointment? (He missed another appointment about 2 months ago - his wife called 20 minutes before his scheduled time to say there was an emergency with their son, and left the message on my machine. His appointment was the middle one, which meant I had to hang around for the next one, 1-1/2 hours later. I did not charge him.)I feel it's up to the client to remember their own appointments. I give them appointment cards for their next appointment, AND I always call to confirm, which I feel is a courtesy, not an obligation.This client is self-employed and knows the value of keeping appointments, but every time he's scheduled to come in, I always wonder if he actually will show up.
