Every now and then I go to a cafe and before I've even taken a sip of my coffee the waitress is asking for me to pay. I must admit I'm quite used to it now, but when I first arrived here I found it rather pushy. It made me feel as though I had to leave as soon as possible. It's true that eating out is relatively cheap in Spain. One of the reasons is that they don't usually hire many serving staff. There is not a big tipping culture here, especially in Catalonia.
