Racist T thug might be homeless man who's spewed abuse before

Sadly, I'd have to ask if you could be more specific. The number of homeless guys cursing up a storm is pretty high in these parts.

2 days ago some loudmouth was on the 39 bus and offered a seat to an older woman who was standing. She said (very politely) "Oh, no thank you." I've seen her on the bus before, and to say she's unhinged would be an understatement.

A minute or two later, he stands up, creepily says "aww, come on, would you please sit, I feel guilty"- she again says "I said, no thank you, I'm fine." He continues to pester her and tries to push her into the seat. She (rightly) flips the fuck out. Yanks free, screams "I SAID NO THANK YOU, LEAVE ME ALONE!", and runs to the opposite side of the bus. The driver, of course, does nothing.

What does Asshole Dude do? Spends the rest of the ride alternately muttering and screaming to the entire bus about how he 'tries to be nice', interspersed with borderline suicidal talk.
