1. Get pissed if you don’t get free food with your drink
This free tapa could range from some chips or olives to an authentic dish of callos, but you have a right to it. After getting your drink, if the waiter doesn’t come back with something to eat, not even after staring at him for a few minutes, you have two options: ask for some chips or decide to never come back. Remember: You’re in a country with more bars per person than anywhere else. Chances are you’ll find another bar on the same street where you’ll be served your free snack or tapa.
