Too much bus exhaust?
I'm not sure if it's the season, or the weather, or just too many exhaust fumes, but I have run into a rash of crappy-mood public transit drivers in the last week or so. This morning I got snarled at because my bus pass wasn't 100% fully turned around the right way so it could be seen. Dang, just ask to see it, no reason to be a dick about it...
