What?!?

A woman comes up to the front of the bus and calmly informs me that I'm driving too fast. Glancing down at my speedo (speedometer; no, I was not wearing a speedo while driving) I see that I'm doing exactly 50kmh. "I'm doing the speed limit" I inform her. "But you're a bus" she replies. "So?" I respond. "You're bigger, you should be going slower." she says. After almost four years of driving buses, you get used to them. I'm more comfortable driving a bus through downtown than my Honda civic. I know how big I am and exactly how much space I need. "I have to do the speed limit. If I drive less than that, I become a hazard to everyone else on the road (I'd also be terribly behind schedule)" I told her. "Well, I'm getting off, my nerves can't handle you" she replied. Fine, be my guest. I'd like to see you find a bus driver that doesn't drive the speed limit!
