Liquid Karma

(We are allowed to say something to a guest if they litter in our drive through, especially if it’s at the window.)

Customer: *dumps can of drink out at my window*

Me: *hands him his change, and some coins fall on the ground*  “Sorry about that, some of them will be wet because people rudely pour their drinks out in my drive through.”

Customer: “Uh, oh, sorry about that.”
