Next time, don't hesitate. And don't ask us afterwards, either. You're a God-fearing American, and shit-on-a-stick, you don't need to take no guff from some smelly Chinaman.
This advice applies to any and all questionable situations that arise in the future. The more you deal with them in an appropriate manner (i.e., not worrying about the other bastards), the better off you'll be. In fact, I'd recommend 2-3 encounters/incidents (isn't that such a negative word??) per day, at first.
You know what really gets me? That fish-mongering slope probably isn't even Christian!
Clint Eastwood had a similar experience on the Warner Bros lot years ago. He had a reserved space... but rarely used it 'cuz he was almost never on the lot. Some dumb jr. exec type (without a reserved space) got smart - figured out Clint was never there... so she started grabbing his space every day.
Then he started a project and was on the lot. He came every day... and kept finding her blocking his space. He left a couple notes saying, "Hi, this is Clint Eastwood. This is my reserved space. You need to stop parking here." She blew it off. (Probably didn't think the notes were really from Clint.)
One day, I'm standing by the front gate yacking with the guard... when Clint Eastwood comes driving up in this giant ass big wheel monster truck. It was HUGE. I thought it was odd... but didn't think much off it as he drove off.
Then a minute later we started to hear the noise... tires grinding rubber... metal crunching... and finally some chick screaming.
Clint Eastwood moved her car himself... drove over it a couple times too before he moved it.
Yup... it was back when I was working on a long gone TV show called CHINA BEACH. It was one of the best tales of carnage that ever happened on the lots... never really made the news either... except when the girl sued.
The best tale of carnage was when Dan Akroyd took over the guard shack at Paramont Studios in his conehead costume and let everybody onto the lot who wanted on. He had gotten pissed off because the guards ran his production into serious overtime by checking and rechecking all of the people he had coming to the set. He wrecked the shack, broke the gate, and was generally a very good gate guard.
The other great mayhem story is the Jody Foster jaw breaker punch. My agent was there for it when it happened.
