Appointment was for 9:45 am, received a call at 9:...

Appointment was for 9:45 am, received a call at 9:30 and said Dr. got a little behind at other hospital so our appointment was pushed back until 10:15, which I understand things happens. We arrived at the hospital and we had no problem getting into a room, with questions answered and IV put in we waited. Around 10:30 we were told the Dr is way behind and it looks like it will be 12:00 before the surgery. Finally at 1:00 pm they are ready for my husband. Once again, I understand things happens, but I own a small business and made prior arrangements for my business to be covered until 3:00 pm, which if the original appointment was kept, there wouldn't of been any problems. At 2:30 I had to leave to go to work. I was promised that the Dr and or nurse would give me a call as soon as he gets into recovery which should of been in the next 20-30 minutes. 4:00 pm rolls around and I still have not heard from anyone. Why did I have to call and ask about him when I was promised they would call, is this hospital too busy. Luckily everything was fine but my question is why is it OK for the Hospitals and Doctors to "Overbook" and have the patient and their others sit around and wait for them. We also have responsibilities and I can't be 3 hours late or else I wouldn't have a business. I don't understand why hospitals and doctors think that our time is not valuable. Do we get to charge you the hospital or doctors for our time?
