No Shirt, No Shoes, No Service — and No Google Glass, Either
Seattle diners who want to take their food-tweeting pictures with Google glass were already facing a preemptively hostile environment; now (in a different restaurant), a diner's been asked to remove his Google Glass headset, or leave. He chose to leave. Maybe Faraday cages and anti-surveillance features will become the norm at the restaurants where things like Glass are most likely to appear.
Don't delude yourself. Surveillance is what governments do. You're not "the anti-surveillance crowd", you're the "anti-photography crowd". And photography in public places is perfectly OK in our society, and that includes restaurants.

How would you know? Google Glass is deliberately obvious, but you wouldn't recognize most cameras as cameras, let alone notice that they are pointed at you.
If you have to ask, then you do not understand what is being discusses here. Please leave, kiddy.
Most ACs are not even worth the keystrokes to insult them. Be generically insulted by this and ignored otherwise.
