There Is A Thing Called "Public Restrooms"

Now here's a story for today. I was bored. I went to kill some time at Tanger Outlets. I was going to get something to eat but the food court was closed. I still stayed for a while and enjoyed the day. As I was getting ready to go back to my car, this car was parked next to mine, and this guy had both of his doors on the driver's side open, and he was standing there. I was wondering why he's parked next to my car with both his doors opened, facing my car. As I walked closer to my car, this guy was pissing on the concrete. I asked, "what the hell are you doing?" What the hell else am I supposed to ask? He said, "I really had to pee." I told him, "Well, there are public restrooms in the mall." He mumbled something to the likes of , "Yeah, but I really had to go.", then he drove off. I checked, but he didn't piss on my car, at least. I was hesitating as to whether or not I should have reported the guy to mall security. When he got back in his car, he high tailed out of there like he was in a high speed chase. Now what gives?
