No, you don't have to pay for the buffer time, or at least, yes, ok, you do have to pay for the buffer time, but the hourly rate of 'buffer time' will only be a percentage of what you pay for actual 'visit time'. The percentage that you pay for buffer time should be a reflection of the probability that the doctor will be busy for that buffer time. I would expect that buffer time would be billable at about 30% of visit time, because on avergae a doctor will be busy for the buffer time about two thirds of the time. Obviously that number is just a guess, but it should certainly be under 50%, if I believe my experiences in doctors' waiting rooms..
