The Seat Offerer
Sure, this guy likes to sit down as much as the next person. But he’s aware that sometimes the next person might actually need a seat way more than he does.
So if someone gets onboard who could use a seat, he doesn’t bury his head further into his mobile device and wait for someone else to be the better passenger. He gets up.
Because he’s not just a considerate man, he’s an awesome man.
