I also showed up late at night and paid on the way out. This is the same guy that was there when I left and he had an unprofessional attitude to me also. I pulled up and rolled down the window, 1st words from him was "that will be $20" I just handed him the money, he brought the pass and I asked a question, his attitude from then was worse, so I said "I will find it on the internet" and drove off. There were no cars in front or behind me, so I wasn't holding up anyone, he could have answered without being a jerk.
I had a great time otherwise .
