CITGO

I'm at citco/pilot in Roxbury NJ, 2 guys came to my truck and banged enough to put a ding in my door. I ask what the heck and he proceeded to raise his voice saying I had to pay 20 or leave. I said it is not posted and on pilot site said General parking 15 spaces. Always says reserved parking meaning pay. Then he proceeded to yell and raise his voice again. I said I'll go pay, but don't ever raise your voice like that. I'm not a child. There are no signs or anything about pay parking. He went to the next truck and the guy said same thing. Then he raised his voice again. Unacceptable. What are my options. For one, I will never come back to this store. Picture is a little round dent from a knuckle or something.
