And then everyone on the plane removes their mask completely while they eat, multiple times on an international flight. So yes, it was literally for no reason at all.
Consider this: it is not possible to make rules that appear sensible in every possible situation, yet if you don't have any rules, you also get no effect.
No, what we have here is exactly that: a rule with no effect. If everyone on a crowded plane removes their masks for extended periods of time, multiple times during a flight, then what exactly is the "effect" of wearing them at other times? Do you imagine covid becomes less transmissible once dinner is served?
Same with restaurants, where we are told we have to wear masks in order to walk to our tables, but we can remove them once seated, and proceed to eat, drink, talk, laugh, and make merry unmasked, because apparently the mere act of sitting deactivates covid.
These are not effective rules in any sense. They are purely cargo cult.
so what stopped you from complying?, the fact that the rule was stupid was sufficient motivation for you to disregard it and annoy a flight attendant enough that you get screamed at and have your trip made unpleasant? (and possibly annoy and make other people uncomfortable as well?)
What would have been your reaction had a passenger politely asked you to put it on properly as everyone else? (asking since I would do that and not sure what to expect anymore)
Why would you scold someone for wearing a mask improperly when you know everyone's about to remove their masks completely as soon as the snacks come out? What's the point of that?
