I beleive that the distinction here is that my mail box is actually a government site (in spite of the fact that this box will be paid for by me, it's design and placement are per government decree). My phone and phone service is a convenience for which I pay. I own my phone and I own my car...most people understand that they have no right to use my car unless I so state.
I'll bet you're as tired as I am of removing those annoying ad sheets from the windshield. What right do these people have to do this?
LOL...Then take the catalytic converters off YOUR car!
