Random people who recognize me

One is the rasta at the Trader Joe's wine store - not that I even go in there that often (honestly). I used to think he just liked to flirt; I (meaning my hair) get a certain reaction from Caribbean men, but sure enough he would single me out even when I wasn't his customer, maintain a certain continuity of conversation, remark on when he hadn't seen me in a while.

Another is the guy in the booth at the downtown/Brooklyn R/W stop. He always waves or smiles or something. Again, I wasn't sure for a long time whether he was really recognizing me or just being outgoing, until he acknowleged me on street level one day when I saw him on his break, grabbing something from a deli. Now, this guy is oddly (for the MTA) young and somewhat hip and something about him screams creepy/pathological. One time, I was getting on the train late at night to go to Brooklyn, I swipe my card in the turnstile and let myself in, kind of deliberately ignoring the booth, and from behind me I hear him lean over, press the microphone button and softly intone "Have a good night..."

And finally, we have the guy who mans the newspaper stand facing the doors of building I come out of when taking a certain shortcut. This guy I actually did think recognized me, as he would always instantly acknowledge me when he saw me, and it does only take about five seconds for me to pass by his stand. Sometimes he would even call out a "How are you?" and so one day I decided to stop and chitty chat for sec. He asked if I worked around here and I said no but I lived nearby. After a few seconds I said goodbye and the next week when I saw him I stopped again, only to have exactly the same conversation ("Do you work around here?"). Annoyed, I started walking away, to which he said "Wait, how can I see you again?"
"I'll walk by again."
