Gunning For A New Way To Say That

(I’m pushing a metal cart around when suddenly I hear a customer start yelling.)

Customer: “GUN! GUN!”

(I quickly stop and look around, along with many other customers whose looks range from confused to panicked. Then, a customer walks up to me with my scanner in his hand.)

Customer: “Your scan gun fell off; I yelled so you could hear me over the noise of your cart.”

Me: *after a moment of regaining my composure* “Uh, thanks, but do you think next time you could do something other than yell, ‘Gun!’ in a crowded store?”

Customer: “Oh… Oh, dear. That wasn’t the smartest thing, huh?”

Me: “I’d certainly say not, no.”
