Facials - Why nobody does them?

[Zoidberg]

Well picture this scenario....next client's arrives and phones when he gets there and due to last guy's facial which destroyed her make up and the bed she has to delay or worse cancel due to it having to redo her make up etc totally not fair on the lady.

Simple, don't advertise them if you're not going to do them and if you do do them let the client know that it's an extra beforehand. Don't blindly accept all clients requests on the phone and refuse when they get there as you never had any intentions of doing it in the first place. Some ladies are booked on services and not on pictures.
