Better than 2 for 1

3 for none, that is.

The story is that I wander in with a fully stamped loyalty card, snap it down on the counter and cheerfully announce that I'll have a free mocha. The girl on the coffee machines sets to work and I banter with the other 2 and a customer.

I notice it seems to take a long time to make my free mocha. And only when I look more closely do I realise that she has made me three mochas. Much hilarity ensues and I do rather well out of my one-off 3 for none deal.
