There you go !
Hell, I'm a big fan of quiet libraries and quiet book stores, where I can spend hours without being interrupted by a silly interpretation of "The Cucaracha" by my neighbor's phone, not to mention fascinating conversations where the guy states what he wants to eat the following evening or which of his clothes need laundry.
I'd also be in favor of executing on the spot every person engaging in a phone call in a theater. That's terrorism against the peace of mind to me ! LOL
