If you're old enough, you might remember when it was still a thing to head to a rock gig and hold your lighter in the air during the big power ballads, turning the arena into a sea of tiny pinpricks of light.
These days what with smoking bans and all that, fewer people carry lighters with them, but the light show is still there – only now, it's much more likely to be coming from a thousand smartphone displays.
Yet if you've ever found yourself watching a gig through the display of the guy in front of you, you might find the trend a tiny bit irritating. And it seems you're not alone, as one music legend took it upon himself to very personally enforce a no smartphones policy at a recent kid.
Classic rock god Peter Frampton was playing a venue in Indiana in the US last week – where concertgoers were given clear instructions that no flash photography or video was allowed.
Yet there's always one person who thinks the rules don't apply to them and in this case, they were in the front row – never a good place to be breaking the rules in front of a prickly rock star.
And after having asked politely and finally having had enough, Frampton came alive (sorry) to take matters into his own hand.
According to Onstage Magazine's Melissa Schickel, who was at the gig: "Peter ends the song, walks over and with a huge smile on his face bends down and says, 'Hey can I see that? Can I see the photos you’ve been taking?'"
There's no prizes for guessing what happened next, and as soon as the phone was in his hands, the Baby I Love Your Way singer hurled it to the rafters. By some accounts, it went as far as 150 feet, so the owner better have had a tough smartphone case to protect it on landing.
If you feel like we do (sorry again), you'll agree that there's nothing more annoying than something who thinks the rules don't apply to them, and while we don't condone phone-related violence, the guy can't complain he didn't have it coming.
And as Ms Schickel said: "With years of experience playing guitar, we just knew he had a great arm."
