What's up TRP,

So the other day I was with a plate at a parking lot, it was a pretty busy parking lot (especially on the weekend evenings). We got in my car and I got on my phone because I needed to GPS my destination home. My phone was acting up so it was taking slower than usual.

All of a sudden I get a knocking on my car window. A lady, late 20's early 30's i'd say. The conversation went something like this:

Her: Hey are you going to move or stay in the parking spot.

Me: I'm going to move, ill back out right now.

Her: Well next time, don't do that - because you're the reason why people think asians like you are bad drivers. (i'm asian)

Me: (As she started walking away) Why are you so rude though? Chill out. (Smiling)

She ignored me, hopped back in her car.

I turned off my car, and decided to be a dick and not give her the spot. She started honking, drove closer and threw a water bottle at my car. She then immediately sped off.

I was pissed but I stayed calm and collected. I stayed optimistic about the situation, and didn't want my plate to see me blow my shit off over a water bottle.

So guess my question to you guys is, how would have you handled this? Did I do okay?
