Always.
the reason is simple. when i was still in elementary, my family went into some recreations area.. and on the last bus going home ( after waiting for a hour ) there is no seat. then some young male get up and offer it to my mom so she can sit and the other guy also stand up so i can sit too.
it almost midnight and it was a 2.5 hours trip. and they standing for us.
that memories always drive me to help others about seating problems.
