Its a shame your tenacity wasn`t matched by the buggars on the pitch
I did something similar myself a few years back at the Nou Camp - had a bloke who couldnt speak a word of English (my Spanish is equally lacklustre) offer me two tickets (season tickets) - we sat right behind the goal in the lower tier.
At half time he vanished only to return with two beers and butties. After the game he went with me all the way back to Place de La Catalunya and showed me where my hotel was. I managed to determine that he had gone the complete opposite way to where he lived in order to show me and my mate the way back. Finally he charged us just £17 per ticket.
Almost as good as winning the lottery
