Men and public pissing

Why do men feel they can urinate in public? Yesterday, I saw a fellow in the grocery store parking lot, with his back to me, the passenger door open, and a stream of water coming out from under his car. I asked my companion a little too loudly, "Is that yob taking a piss?" She said, "Yes, I believe he is." The yob turned to me and said with an amused shrug - while still holding his johnson - "Sorry." That fellow wasn't sorry for piddling in the parking lot!
I asked my companion, who is savvy about all things international, if in some other cultures men keep their dick in their pants. Her response was she had not yet found a culture where men don't piss in public. They do have lots of different terms for weeing and their willies, though, she added.
OK - here is my message to the fellows on behalf of all womenkind. (This is what I love about having me own blog. I can make grand statements like this!) We, women, know that having a john henry is 'handy' and maybe even kinda fun, and you can write your name in the snow and all that, but use the loo like the rest of us, you bunch of goats.
