So I saw the aisle strategy defeated today while riding the train downtown to court. A young woman gets on the train and a young man sitting on a side facing seat relinguished his seat. Then in the forward-facing row adjacent to these seats, was a guy that was using the aisle seat strategy. The guy that just gave up his seat tapped the seat hog on the shoulder and made him relinguish the window seat. This actually put the shoulder tapper in a much better position as the aisle guy would feel social pressure every time a woman or elderly person got on the train. The shoulder tapper was now safely trapped by the window and no longer felt social pressure to give up his seat. Brilliant tactics and timing by the shoulder tapper given the way the train usually fills up.
