Dear Doctor-Waiting-Room Jerk who's complaining about the long wait,
Thanks for letting us all know you're really important because it's 9:40 and you have a 10:00 call and are upset because haven't gotten in to see the doctor yet.
I know you're dealing with a he-said, she-said kind of thing. The nurse says you were 25 minutes late for your 8:45 appointment; you claim you got here before 9:00. The point is though that you were late.
Haven't you tuned in to any of the problems in health care over the past decade (or more) that talks about how little time doctors have for individual appointments? If you're even 10 minutes late, you've pretty much missed your time slot. You want a same day appointment? Wait it out, buddy. Since you've wasted their time (and their dime), you're now at their mercy. Suck it up.
I realize your call was probably earth-shattering, but since you screwed up their schedule, you can wait until 9:36 to get fit in. If it's important to you to see the doctor, your call can wait.
Oh, and since you're scheduling your follow-up appointment for first thing in the morning, how about setting your alarm now so that you can get there on time and not mess up the day. Again.
Please and thank you.
