Fine - "Parking"

Good morning,

I recently went to the McDonald's in Downtown Dallas and decided to eat dinner in my car in the parking lot next door.

About 2 weeks later, I got a notice fee in the mail that I need to pay $90. Does anyone have any experience with this?

I was not parked in a spot and out of the way of anybody that would need to use the lot. I was only there for about 10 minutes.

My McDonald's Adventure turned into a $100 big mac.
