Last night on the train. GF and I were seated near the middle door. Skeezy dude gets on at the front, barefoot and holding a lit cigarette, obviously chemically impaired. Walks past us a ways, turns around, and stands in the aisle near us. GF was looking at her phone, I was avoiding eye contact with skeezy dude, but saw in the window reflection his hand was down his pants.
We both noticed about the same time, and moved to another area with more passengers. I could just see skeezy dude from our new seats. He laid down in the floor, on his side, his legs across the aisle. Anyone wanting to go between sections would have to encounter him and his filthy bare feet.
We mutually decided we didn't want our NYE ruined by skeezy dude, so we didn't report him; spending our evening giving details to transit police wasn't our idea of a fun time. She is former NYC Transit so she knew what speaking up would set in motion. Also nearly every transit cop was already on duty establishing a conspicuous presence on all the rail platforms (except the one where skeezy dude boarded, which is the only underground station in the system so they couldn't sit in their vehicles with red-and-blues going).
