Lots of ppl on my flights didn’t wear masks and no one said a thing to them. The flight home was dark anyways so no one could really see your face but even on the way out the air hostesses just left it and didn’t even ask, they didn’t bother anyone at all walking through the airport either. In the Uk if you confront anyone you can be done for £5000 by the discrimination act they are probably more cautious now. The stupid thing wasn’t probably them taking photos and making a scene.
