Holy Pretzels, Batman! There’s Been An As-salt Down On Seventh!

I’m volunteering as a food runner in a concession stand. The rush hour at the arena has just finished and we haven’t had a customer in about fifteen minutes. The cashier I am working with is stationed right by the pretzel station and a lot of the salt has fallen onto the counter. Bored, I start to move the salt around with my lanyard card. My cashier sees what I’m doing. 

Cashier: “Are you doing lines?”

Me: “No.”

There’s a pause.

Cashier: “Are you making the Batman signal?”

Me: *Pause* “Yes.”
