AFAICT, they tell you to put the window shade up during landing in order to wake people up and thus to get out of the seat and off the plane as soon as possible

AFAICT, they tell you to put the window shade up during landing in order to wake people up and thus to get out of the seat and off the plane as soon as possible. I've never had them ask to open window shades at night (possibly because they're not closed). Which is perfectly fine with me.
