Here's what 5 Point Cafe posted on its Facebook page last week, first uncovered by GeekWire:

"For the record, The 5 Point is the first Seattle business to ban in advance Google Glasses. And a** kickings will be encouraged for violators."

That's in part because of the culture of the bar, 5 Point owner Dave Meinert told Todd Bishop of GeekWire. He says it's sometimes a "seedy" and "maybe notorious place."

Meinert admitted to GeekWire that it's somewhat of a joke, and he first posted it to get a reaction out of people. But it's still serious at the same time, he says.

Already, the bar doesn't let people film or take photos of people in the bar without their consent. People have started speaking out both for and against the ban on Facebook.
