I always found that if you actually ask the person behind you if it's ok with them, before you recline.This is hilarious! You can recline your seat whenever you want! Obviously put it up for meal service, but you can’t moan any other time. Can’t stand part time travellers. Bane of my life.
I used to fly all over the world for my job, and if you ask, then that is just good manners - and I never had anyone say no by the way.
Good manners costs fuck all.
