What's the point of an appointment if you sit and wait 45 minutes.

Update:
So after an hour I walked up again to ask if it gonna be much longer and guess what?
The lady we're here to see is sitting all alone and available. Matter of fact she is sitting and waiting for us but thanks to some idiot who told me she is with a customer I am waiting looking at her and she is waiting for us.

We walked in and I said we have appointment and we were told to have a seat because she was busy. What an idiot.
