Personal Space and the Kill Zone

OK. So being half-Chinese I can accept the fact that my fellow Asians find comfort in shopping and existing in the armpits of others. My Mom and some of my friends can't stand crowds. I for one, can appreciate shopping in Chinatown with old ladies pushing at my rib cage to haggle price on foods. I don't mind. I do mind when people spit uncomfortably close to my feet. Now, on the same note I need my personal space. I'm not trying to be hypocritical.
I can deal with crowds because they are in and out of my face and it's part of the ambiance; invasion of my space however, is not acceptable. A few examples. If I don't know you and you tap me on the shoulder, that's ok. If you breathe down my neck or touch anything below shoulder leave you have officially entered the "Kill Zone". My Kill Zone is as big as my arms length all around me. No one can enter the zone unless you have known me for just about EVER and/or I trust you. (rare and few).
Having said all of that, it has become apparent that in LA; no one observes any kind of personal zone. Case in point, parking attendants. At work we have to park in a boat launch parking lot a few miles away. And every morning I park there the freakin attendant reaches past me to place a tag on my dashboard. Normally this shouldn't affect me but my car is very VERY small. Therefore anyone reaching into my window has to have passed my face within a few inches. I have tried everything to deter this. I started with the subtle hints like reaching my hand out the window before I pull up, but he is apparently hand blind and refuses to acknowledge it. I tried the roll my window down part way, but he forces his fat hand through, one day i thought he was going to break my window he forced it so hard. I even asked the guy, here's how that went:

Me: I can take that (my arm fully extended and window down)
Dude: (Forcing his way past my hand towards the dash) GOOD MORNING!
Me: Um (Intercepting his hand before he places the ticket down) I can actually take that. I like to place it there myself, Thank You.
Dude: Oh ok (steps off the curb and shoves his arm up to his shoulder further in towards the dash.

Obviously that didn't work. I have found that this phenomenon occurs in most parking garages down here as well. People just don't get it. I really don't want to have to pay for a new window either. I know how much that is going to cost if it breaks. *grrr* People need to get out my face!
