A San Francisco woman was allegedly attacked and robbed for wearing Google Glass in a bar on Friday night. Sarah Slocum told local CBS affiliate KPIXthat as she was demonstrating Google's device for another patron, two women angrily confronted her. Soon after, a man at the bar tore Glass off of her face, though she later retrieved the $1,500 Explorer Edition unit. According to Slocum, video footage taken with Glass shows the incident and the perpetrator's face. Unfortunately her smartphone, purse, and wallet were also stolen during the ordeal, and those items haven't yet turned up. "I got verbally and physically assaulted and robbed because of some wanker Google Glass haters," she later wrote on Facebook. One of the assailant's friends accused Slocum (and presumably other Glass users) of "destroying the city," according to a San Francisco Chronicle report.
