Something new has happened to me now a few times while flying a German IT/LoCo carrier to the UK which I use approx. all 2 weeks:
When having a seat at the overwing exit I was personallyadressed by the F/A after the brief whether I knew how to work the exit.
Funny though, seems not to be official as this happened maybe 4-5 times out of the last 15-20 flights.
Not a bad idea - why not do so as a standard operating procedure?
