Q: How long should you wait in your doctor’s office for a scheduled appointment before you give up–and what’s the best way to express your displeasure?
A: Generally, medical offices aim for wait time of no more than a quarter hour to half an hour. After 20 minutes, you can ask how long the doctor will be, and decide whether you’d rather stay or reschedule. After 30, it’s reasonable to leave-if you feel you must. Then write a polite letter, factual letter to the practice’s head; most offices address written complaints.
