Missed Appointments

The scenario...you have a doctor's appointment scheduled, but you happen to have the flu that morning and you stay home in bed. You get a bill from the doctor for a missed appointment...because you were sick. That bill is something stupid like $160...more than the doctor would have billed the insurance company if you showed up for the appointment. OK...so days have gone by and you're healthy again...you rescheduled your appointment and the time for your new appointment has arrived. You go to your appointment and the doctor is out sick. You are AT the appointment...writing that co-payment check...and you find out that the doctor is out. Sick. Just like you were the first time when they charged you for missing an appointment. Shouldn't you be able to charge them for a missed appointment? I think so...
