I'm going to take a parking spot and park my car there.
Why are you taking the parking spot?
I'm in hurry dammit, do you know how many urgent things I have to do?
There's nothing wrong with claiming a parking spot. You should make sure no one else is trying to pull in to the spot first so you avoid an accident.
I'm going to use my phone GPS as my witness.
You need to park somewhere and there's nothing wrong with finding a good spot.
