Going Postal

This post is especially for Shelley's Mum.
Having been a few places and sending postcards back home, after we had gotten back to the UK, my Mum commented on how she would like to receive a post card from the actual city that we were in. "OK," we said, "no problem." We wrote out several postcards and then one evening on one of our walks decided to find the Post Office in Barcelona to get stamps to send said postcards.
Amber had the map and was navigating our way through the winding streets and alleyways of the Gotic Quarter (Gothic). As the alleyways started getting more twisty and the area more dodgy looking I started to get slightly concerned about where we might actually end up. Amber however has a GPS unit inbuilt (complete with Europe upgrades) and before too long we ended up in front of a humongous building that looked more like a Greek Temple than a Post Office. If any one reading this has watched Terry Pratchett's screen adaptation of Going Postal then you wouldn't be barking up the wrong tree if you compared the P.O in that to the P.O we found in Barcelona.
Photographic Evidence:

And now for Terry Pratchett's version:

Anyway we walked inside and the inside is as impressive as the outside with lots of people inside little glass booths around the edges of the building and a massive big empty space in the middle. We look around for a bit wondering how to best go about getting what we came for.
Observing other people we noticed them walking up to a little machine and pressing a number and then the little machine spits something out and they walk away. So we approach the machine.
There are three buttons we could press.
Button 1) Gobbledygook in Spanish
Button 2) See Above
Button 3) Imformacion
Out of these 3 options the only one we understood was number 3 for information. We press three. A little ticket prints out that says (we think) see the information desk. We look around for that magic 'I' sign that is known to tourists everywhere. Once located we walk up to the desk to find it is empty. Hmmm on to plan B. We remember seeing a lady sitting at a desk as we walk in so we walk up to her.
Me: "Excuse me do you speak English?"
Lady: "No"
Me: "OK thank you".
Right so for those of you who are counting we are now up to Plan C.
Walk back to the little machine. Randomly pick Button A. We get a new ticket. it has a big number on it and nothing else that we can decipher. Amber looks up at a screen it says A)597, we look down at our new ticket, it reads A)614. Hmmm we look at each other and realise that we may have a bit of a wait, also that we don't even know if we have got the right ticket for what we want. After a brief discussion we decide that Mum will understand. Right now on to the Sangria.
