How long is long enough to wait for the hairdresser?

Appointment was supposed to start twenty mins ago.

I'm still waiting for her to finish someone else. How long do I wait?

Hopefully they apologised when you arrived and gave an indication of how long. If not you could ask the receptionist?

I presume they've made you a nice coffee and given you a magazine while you're waiting?

I guess it depends if you have to be somewhere?
