Fuck those guys. I had the same thing happen to me. I walked up to a parking enforcement person (who was 100% illegally parked in her vehicle just playing games on her phone) and pointed directly at my car and the parking sign and asked if I was legally parked and if I would get a ticket and she said I was good... Not 10 minutes later she went and ticketed my car.

I fought it but DC parking is full of twats and they straight up denied any appeal.

Then they wonder why everyone hates public officials and any type of authority figures.
