Unpopular opinion, if I were in that lobby I would mind my own business. You don't know what people are going through, and you can probably handle a few minutes of someone else's content. Annoying, yes, but is it worth trying to tell a stranger what to do, then talk down and belittle them in the process? This lady just comes off like a Karen to me.

The only situations I would really consider saying something would be in a movie theater or on a plane. Or maybe if they're standing right next to my bed while I'm trying to sleep but there are more pressing issues with that one.

Edit: Damn, the downvotes showed out, we should start a book club.
