How long would you wait...

They bill you if you miss an appointment.

I think you should be able to bill them if they do, or have your bill discounted.

My doctor's office has a sign on the wall asking patients to let them know if they've been waiting longer than 30 min.

I was one day and let them know- clerk said "he's running late" and that was it.

WTF is the point of that sign????
