San Francisco bar bans Google Glass for fear of secret recordings
A bar popular with a high-tech crowd in San Francisco's South of Market neighborhood has banned patrons from wearing Google Glass, the local CBS station in the city reports.
A sign posted at the Willows at Folsom and 12th streets features a picture of the wearable computer with the familiar red circle and a slash over it, along with a message saying customers “have expressed concerns with being recorded while enjoying themselves.”
patronというとフランス語から入った意味（"a wealthy or influential supporter of an artist or writer"--Webster）が強い言葉ですが、バー、パブなどの「常連、おなじみさん」の意味で用いられることもありますので注意！（UG）
