So I'm on the #36 Broadway bus today, around lunchtime.
An off-duty CTA driver gets on, takes a seat in the back and starts eating a sandwich. After a few minutes the bus stops at a light. The off-duty driver glances out the curbside window, jumps up, and runs to the back door.
She opens it, leans out, and yells "Hey! HEY!" at a skinny young guy on the corner who is wearing clothes that have not been recently laundered.
He walks over and she hands him the other half of her sandwich.
He says thanks, she goes back to her seat, and the bus pulls away.
