'm kinda wanting to go down and ask them for a detailed billing. I think I have the right to know what the fees are for. Is it billed by the hour? Because then they're either charging $500/hour or I got charged for my waiting room time.
No, you didn't get charged by the hour for time in the waiting room. If you do ask for a detailed billing, what you'll probably get is a list with one entry: Office Call.
