Get Off Your Phone
Was on a band trip in Hawaii, visiting some park (can’t remember which) listening to a tour guide while this guy in a tie is constantly jabbering on his phone about business. I say to him, “Get off your phone and stop ruining everybody’s, including your family’s, vacation.”
He stuttered something into the phone and quickly put it away. The tour guide kept on talking.
