Yes, Spain IS getting more expensive. But so is Britain and the rest of Europe. The fact is, when you get served a spirit, you get twice the quantity as you do in Britain.
Drink wine, it's far cheaper and much nicer!
Also, now that we have a national minimum wage in Europe, wages are higher in Spain. You can hardly blame workers in Spain for wanting a decent liveable wage. Especially when they often get hassled by rude British people spending money and get plastered every night. As a consequence, prices will go up in bars. The food in restaurants is still far cheaper than in Britain! You can still eat out cheap, you can get a menu del dia from €7-€10!
Yes, it is cheaper in Turkey, but they aren't in the EU, and the workers don't have as many rights. The general cost of living is also considerably cheaper than in the rest of the EU.
If you are complaining so much about Spain, go to Turkey then.
