update: more bus bloopers

--When you think there's a seat free in the back and you're the only one standing and walk all the way to the back only to find that there isn't one.
--Vice versa:  there IS a seat free in the back but there's someone who won't go take it standing between you and the seat.  Even worse if you can't quite tell, but are pretty sure there is one.
--You push the button and nothing happens.  So you push it harder.  Nothing still happens.  You don't know if the button is broken or if the driver's got it turned off because he's already planning to stop.  Or what.
