A man who thought he was hopping into his hired ride got a nasty shock Friday, when the driver turned out to be focused on something other that customer service.

It was 4 a.m. Friday when a 30-year-old man got into a car near the Hayes Valley intersection of Buchanan and Hayes Streets.

According to the San Francisco Police Department, the man believed the vehicle was transportation he had hailed via a smartphone app, but it was not. Nevertheless, the 30-35 year old male driver demanded that the man give him some cash to pay for the ride.

As the aspiring ride-sharer pulled out his wallet to pay for the impromptu lift, the driver, police say, "bit [the victim] and took all the money from his wallet."

The sharp-toothed suspect then punched his abortive customer in the face. Fearing the worst, the victim scrambled from the cab-that-wasn't, dropping his cell phone in his haste to flee.

The suspect, police say, snatched up the victim's cell phone, and fled in an "unknown direction."

The victim suffered non-life-threatening injuries to the hand, according to the SFPD. As of Monday morning, police say, the suspect remains on the loose, and no arrests have been made in this case.
