What would you do if someone stole your parking spot and gave an unsolicited apology?

I was in a parking lot looking for a spot. This jackass whips around the corner in front of me, driving entirely too fast, pulls right in front of me and takes the spot I was planning to park in. The spot next to him was still open, although it was for compact vehicles and was harder to enter. No problem, though, as I'm driving an old beater pickup truck. So get this - I pull into the spot next to him. He gets out of his car and says, "I'm sorry, I thought you were going straight." I tell him, "Whatever." He then gets pissed off that I didn't accept his apology. The moron has a neck tattoo and sounds like a stupid vato, so I quickly surmise that talking with the "reformed" cholo would be a complete waste of time, so I say, "Look. I didn't say a word to you. You're the one who started talking to me." He then says, because "men to men should apologize." He then walks toward me aggressively for a second like he wants to attack me and says, "Fuck you, you little bitch." I replied, "Whatever, dude" and rolled up my window. The freak walks off into the mall and I went and did my thing.

So, what would YOU have done? Frankly, I wanted to kill him.
