Quick, get it while you can!

Craft distillers LoneWolf have popped up a gin and tonic vending machine at Old Street for two days only.

To unlock a free can all you need to do is tweet @LoneWolfSpirits, using the hashtag #TheWolfOfOldStreet.

Then show to security and receive your token for a free G&T! Awesome…

But, you better be quick as the free drinks are only around for a limited time.

The free G&Ts are only available from 12:30-10pm today, and 12:30-5pm tomorrow, in Old Street underground station.
