Whether it's the subway or the bus and the doors are closing, please do not run up to the doors and put a body part in its path! That bus driver also has to look for traffic when they're leaving the bus stop and believes the door has been closed. You have to realize that the bus driver is basically customer service rep, a token booth clerk, a train operator and a conductor all rolled up into one! That's four jobs they have to perform at every instance they're driving that bus!
