On a cross town bus on the Upper East side:
A woman steps onto the bus and is told by the driver that she has to use the new ticketing system (which is off the bus.)
She steps off and goes to the machine, confused about this process, trying to make it work.
A man on the bus toward the front, got off the bus calmly and quickly, showed her how to use it (she did it herself) he lets her on the bus ahead of him.
