On CX, attendents bring a stick and order the shade to be closed according to protocol, or they will close it with the stick. If AA FAs had that stick, they should give that pax (who refused) a good slap on his backside

Like it or not, but when an FA says "close it", you have to.
I can understand having it open at night (I like using the window to cool my pillow), but during the daylight, keep it shut if bothering others.
