As we've pointed out before, driving a cab in San Francisco is about as dangerous as being an unarmed cop.
Sadly, one local cabbie learned just how ungrateful (drunk?) passengers can be when he picked up a rowdy trio at the corner of Valencia and 18th streets early Tuesday morning.
The trouble started at 1 a.m. after the 58-year-old cabbie picked up the three men. The passengers began arguing among themselves, until one started yelling at the cabbie. This passenger then grabbed the driver from the backseat and started choking him, according to police reports.
The cabbie pulled over and hopped out of the car, followed by all three passengers.
