1130 routine appointment turns into two-hour wait....

1130 routine appointment turns into two-hour wait. Good doctors, great nures, but admin people clueless about intelligent scheduling. The people running NUH have zero respect for patients' time, and appear to massively overbook doctor schedules.

Then, after consultation, I was the only person left in the waiting area.

Me: Can I pay? I've been sitting here thirty minutes.
Gruff admin woman: You must wait. I'm dealing with a cancellation.
Me: I've been here thirty minutes, waiting.
Gruff admin woman: I'll send you the bill!
