Reminds me of a saying something I saw recently.
Dance like no is watching.......because they're not. They're checking their phones.
There is another one. When you go out with your friends, everyone puts their phone in the middle of the table. First one to reach for theirs buys a round.
That would put an end to it for most people if it meant buying a round.
Like back in the day when most people wouldn't answer their phone because cell phone time was so expensive.
