Washington is full of busy, self-important people, some of them actually important, but very few who would routinely keep you waiting 45 minutes in the anteroom for a long-scheduled 15-minute appointment. If the President himself left you twiddling your thumbs outside the Oval Office for three-quarters of an hour, you probably wouldn't mind -- but you probably would get an apology. Yet that kind of wait is common, without apology, when you visit a doctor's office.
There is no excuse for this. Other professions have meetings of unpredictable length and accommodate by not overbooking. Surgery and emergencies? Pshaw, the last time...
