Don't bother with an appointment
I made an appointment for my two children to get haircuts with a stylist, one scheduled after the other. The appointment was for 2 PM. When I checked in at 2, I was told that the sylist was running ten minutes late. At around 2:10, another employee came out and told us that it would be at least another 20 minutes before the stylist would be with us, and that we could shop and come back. I agreed to return at 2:30. At 2:30 I returned, waited another 5 minutes and then asked the receptionist how much longer I would have to wait for a haircut. She checked with the stylist and said that it would be another 10 minutes. At that point I told the receptionist that I wanted to cancel my appointment as I would have waited 45 minutes for the sylist, assuming that in fact I would have actually seen her in 10 minutes and not had to wait any longer. The receptionist apologized and said that the client that was with the stylist had requested additional services and that was why the stylist was running late. At the salon where I get my hair done, had I requested additional services and the stylist was booked, I would have been told that the services could not be performed by the stylist, even though I am a long term client. So, feel free to make an appointment, but if anything else comes up for your stylist, know that you'll be waiting for a while.
