Once in domestic FC, I boarded late with 2A assigned to me to find some guy already sitting in 2A. I called the FA who asked to see his boarding pass. It said something like 29E and he tried to pretend that he had just taken the wrong seat by mistake at which point I loudly commented that it would be impossible to confuse those seats as he did the walk of shame to the back.
