A San Francisco Treat

San Francisco has finally decided it needs to impose standards : The transit agency's new anti-gross law goes into effect today [May 6, 2013] ... for smaller infractions such as pooping on the escalator, you'll have to accrue three citations within a period of 90 days before you're actually banned from the trains ... more advanced morons who stab, shoot, or beat others only get one chance ...

And just in time for summer, too.
