There’s a video going around of Reba McIntire reacting quite differently. She stops her show, happily and good-naturedly poses for a selfie with a fan. The audience loved it.
These performers take themselves too seriously. It’s supposed to be entertainment, not brain surgery.
There are videos out there showing performers taking phones from the audience to get close ups of the band and out across the audience. That’s what good decent people do. Nasty performers do what ML did.
