This ID Is Sub-par

(I am the customer in this story. I am checking out with a few items of food and some beer. I keep my ID and subway card in the same pocket of my wallet.)

Cashier: “Could I see some ID?”

Me: “Sure!”

(Not paying any attention, I hand her my subway card.)

Cashier: *holds card while staring at me, waiting for me to notice it’s not a driver’s license* “Um…”

Me: “Oh, oops! Sorry!” *hands her my ID*

Her Coworker: *while bagging my groceries* “Now, if it was a twenty, that might have worked!”
