Last week lager lovers in Glasgow awoke to unusual messages on billboards across the city, encouraging them to message the brewer’s mystery number.
Many said they received some free beer and unsurprisingly, others were disappointed they missed out.
However if you're planning on heading in to town today or are making your way to the office - today was a good day - even if you had to get out of bed earlier.
From mid-afternoon today, Glaswegians can pick up a free pint from a booth set up in the city.
Innis & Gunn’s ‘If You Know, You Know’ beer booth is in a secret location - though it's not too hard to figure out where it will be.
Fancy a free pint? You’ll have to find our booth first. Located in Scotland’s busiest city, but not the capital. The street name? Fill in the blanks: _ _ _ _ Travolta

The booth is set to stay in the city from until 5pm today - but can you crack their code?
In order to redeem your freebie, all you have to do is figure out the clue and once 'you know' where it is (hence the name), you simply have to answer a question about the brand and voilà - a pint will be yours.
In a reply to the award-winning brewers tweet, one user said: "Thought it was illegal to drink Alcohol on the streets of Glasgow?"
However the brand cleverly responded it had found a loophole.
If you manage to crack the code and claim your free beer, let us know and tag us on twitter.
Best keep you're eyes peeled in case they return...
