Your welcome mate. The app goes by the emi number of the device. Another pub was also doing a similar promotion literally 30 seconds walk away, so I had 6 free pints in one night lol. Very rare but when you get deals like these it makes a great free night out (y)
That's great thanks for sharing!
Like to add that you don't have to have a phone SIM, I had 2 android phones on me plus a tablet and got all 3 in the same night
