I was fortunate enough to have been allocated a seat by an overwing exit on a recent flight with Lufthansa. One of their normally horribly cramped A320neo aircraft, but on this occasion I had plenty of room - which was just as well as the chap in the middle seat next to me looked like he could have tried out for the Harlem Globetrotters!
After everyone was seated, the flight attendant came over and gave me a brief on the procedures to be adopted in the event of an evacuation and directed my attention to the instructions affixed to the seat in front and to the exit itself. She did this in a clear, courteous and professional manner.
Quite why anyone would refuse to listen to the instructions for passenger evacuation is frankly beyond me.
