I don't know if the times have changed, but if the staff at the restaurant I've been twice knows something I did not tell them, I would not be particularly comfortable with that.
I was at a restaurant a while back and looked over at the hostess' iPad. It had my Twitter avatar on it. I never told them my Twitter handle, but it is associated with the email I used. Do public musings count as telling someone something?
Maybe the next restaurant you (the personal you) go to will look up your email address, find this post and just serve you food.
The defense is that it's to make the experience better, the reaction is that it won't...
I didn't say I don't want them to read them. I said I don't want them to provide me evidence that they read them.
I saw you enter your apartment, it's public information. But I bet you'd feel pretty unsafe hearing that.
