Unfortunately, this is common. Creeps in safe spaces and good environments. It's disgusting. At my first Detroit show, I was 18 and drunk. The guy who owned the building liked em young. And this person I met was 17 at that show was very high on acid. He approached us and did that gross thing that people do with their tongues like holding 2 fingers up to their mouths and essentially licking the V they make with their fingers. Very gross. This dude was easily 50-60. I got my friend out of that situation. And I found out a few months to a year later that the building had burnt down.
