>Actually they have thrown out people even in Paris McDonalds for wearing a Google Glass.
The incident you're thinking of was Steve Mann being assaulted and thrown out for wearing his own custom digital eye glass, about a year before the Google Glass developer release.
I also haven't heard of frequent incidents involving "sensitive areas". Some incidents, yes, but definitely not enough for me to categorize it as a trend.
Unless what you're describing was a later repetition of a 2012 incident, that was actually Dr Steve Mann being kicked out for wearing his EyeTap - which is physically bolted to his head and cannot be removed easily. Nothing to do with Google Glass at all.
So it's socially inappropriate because it's not allowed by a gigantic corporation (that films everything we do at their restaurants), as well as stuck up fancy institutions that will scoff at your shoes and not let you in for that?
And just try wearing it in some sensitive areas (e.g night-clubs, expensive restaurants etc) around the world and see what happens...
