Driving with my family, we reached the toll plaza at RFK Bridge, and there was apparently some problem with our ezpass. Of course we didn't have any cash, so the officer lifts the arm (they had those in olden days of pre-July 2017) and tells us to pull over to the side after the toll plaza.
A few minutes later she walks over and tells us we can go. Seeing our puzzled looks, she points over at another car going through the plaza and tells us the driver of that car paid for us.
We got a quick look at the guy and were able to wave our thanks. He appeared to be a 30-something Hispanic man. We were totally in awe of this man's random act of kindness and resolved to pay it forward.
