Flew on a long haul flight last week with a major UK airline. As far as I was aware masks are mandatory on a flight.
Two men got ion the plane and sat two rows in front of us with their masks around their neck. The flight attendant asked them to put them on but they said they were exempt 
which beggars the question of why they had them at all? Shortly after takeoff another man took his mask off and spent the rest of the flight standing chatting to a passenger across from us with no mask on for the rest of the flight. I was not aware of him being asked to put it back on. Meanwhile we’re struggling with keeping our masks on for 7 hours!
On the flight back yesterday, my mask slipped down my nose so it wasn’t covered when I was trying to find space for my cabin bag as the lockers were all full. I got the attention of a flight attendant to ask him where I could put my stuff but he said very patronisingly ‘put your mask on properly then I’ll answer your question’. He then walked straight past a passenger with his mask around his neck and didn’t say anything to him. There was a different flight attendant with his mask only over his mouth not his nose the whole flight!
I’ve just read about a woman being removed from a flight for refusing to wear a mask.
WIBU to make a complaint about this to the airline?
