A margarita and a margherita and a...

One of the bars near my flat runs a two-for-one offer on pizzas from Mondays to Thursdays. It also runs a two-for-one offer on cocktails before 7pm.

So if you were to go at 6pm on a Thursday, for example, you could order a margarita and a margherita, and get a margarita and a margherita free.

That's the spirit! (Photo from Flickr)
