Green commuters of another kind

I know for most people, getting on the bus means getting on the bus; who cares where you sit, right? But, what I can't stand is people who fail to notice—or just flat out don't care—that a line has formed near the bus sign. It's pretty annoying when a group of people walk straight up to the bus doors when they should be at the back of the line.

I guess that's the price us green commuters have to pay.
