I was serving in the concession stand at a high school football game a couple years ago. Now keep in mind the stadium is literally across the highway from the entrance to the Air Force Base located in our town. One might think locals would have some idea of proper anthem etiquette. Nope! Most of us working the stand were either currently military or retired military. When the anthem plays the concessions typically stop. I stopped serving and the fella waiting to order blew up on me but I didn’t acknowledge him until the song ended. Really he made a fool out of himself. I was rather surprised, kinda proud actually, when the guy in line with him blew up on him after the anthem finished and told him how stupid he looked. He was still pointing and mouthing him all the way back to to their seats in the stands. We laughed about his lecture the rest of the night.
