MATS price gouging?

Some more details:
I got to the ticket counter, and told the woman I wanted to put my car in the Car Corral for today. She asked if I pre-registered, or some such. I said no, I just drove up here. She gave me a dirty look and rolled her eyes, and had a very bad attitude. She told me to fill out a form, and it would cost me $120. I said I just want to put my car in the Corral for a day. She repeated, $120. I said no thank you, and walked away.
