How the heck are we still not getting how a mask is mandatory in a plane?
Look, I get this is a free country but she bought the ticket. The ticket says you must wear a mask. And by not doing so, you can get kicked off the flight.
I will however point out how 'sly' the person holding the phone is trying to be...because she sure doesn't want "Maskless Karen" to see she's holding a phone...then it would've been even WORSE!
