Handing him his lunch
I've ridden the CTA long enough to know that one cardinal rule is that you don't touch another person's stuff.
So I was somewhat surprised to see a woman in her late 20s beeline to the only available seat -- because a lunch was occupying the seat -- pick up the lunch, and uncerimoniously dump the lunch on the lap of her neighbor. And it woke him up.
I think he was too dazed to take much offense, even though he shouldn't.
He went back to sleep and she got her seat.
