On the checkout line at a store and the woman lbehind me has her cell phone in her hand in the air on speakerphone. She’s not talking on the phone. She’s listening to something. I can’t tell if it’s a social audio app, a podcast, or somebody else’s conversation. (Because it’s in a different language.)  She seemed completely oblivious to the fact that no one else wants to hear her speakerphone. (Or at least I don’t) I’m finding this more and more common and it’s bizarre to me.
