We've all seen it happen before-- somebody either tries to get on or off MUNI in ways that they're not supposed to and when the MUNI driver actually tries to enforce the rules, they get aggravation for it. This YouTube clip, caught by SFist's own Matty Matt, is a clip of some dude trying to get on MUNI despite having an expired pass. Things, however, quickly escalate to the point where the guy has the entire bus yelling back at him and a cop shows up. And the dude still refuses to budge. The video even has subtitle goodness to go with it.
The clip is one of those things that gives us a lot of sympathy towards MUNI drivers, most of whom try to do the right thing but always wind up getting damned no matter what they do.
