He sounds like little more than a toddler having a hissy fit. "Well I don't SEE anything that says I can't wear it. Just cause you work here doesn't mean you're the boss of me." Um, how about common freaking courtesy? Do you really have to be wearing your Glass constantly? Just cause I don't see a sign that says I can't come piddle in your wine glass doesn't give me the OK to do it. Admittedly, I do get irritated by people that just can't put down their mobile device for 10 minutes without getting twitchy. You want to visit a restaurant that allows Glass and whatever else? Fine, go open your own place. Otherwise, yes, you are subject to the "rules" of the restaurant you're visiting.
Biggest thing though...have common courtesy. If you've been asked nicely to do something at a business, do it. Their place, their rules. If it's truly unreasonable or discriminatory, then make a case out of it. They ask you to put away your mobile device, speak more quietly, dress in certain attire...do it! But if you're going to throw a fit solely because you choose to be a self-centered ass, then please lock yourself in your house and stay away from the rest of us.
