While I agree with the comment in general, my norm is to immediately cancel and reschedule or go on without the person.
The victimization aspect (3 wasted hours) could also be avoided by not passively sitting and waiting to start.

Also, mobile phones .. the person being late will generally call (and maybe during 3 hours (!!) the person waiting might ring and find out whats going on).
Waiting, doing nothing for 3 hours and then complaining about it seems a bit passive aggressive, I think I would wait an hour tops.
Also, not every employee can accomplish that much in 10 minutes. A support or business person could fire off an e-mail or two, but an engineer suffers when time is broken into small chunks. Engineers are also paid pretty well, so when you're talking about 3 hours of "engineer-time" wasted, the cost to the company adds up.
