Backpack Attack

(I order a coffee from a kiosk, and go to the pickup window to get it. Just as I pick it up, the man next to me turns around, smashing his backpack into me, and spilling half of the coffee. He then stands there, unmoving, with his backpack inches from my nose. I lift the flap on his backpack, and pour in the rest of the cup.)

Me: *I ask the barista as I take out my wallet again* “May I have another coffee, just like the last one?”

Barista: *with a grin* “Absolutely, but you sure aren’t going to pay for it; that was awesome! Come pick it up at the order window; his backpack’s probably full by now.”
