Tapa culture is actually sharing some quality time while having a drink and some food. It's not about the more food the better. We use to order just one tapa per person and the next one once we are done with it. Otherwise they would get cold or you get full or want to go somewhere else... Anyway is very common, even in restaurants, that if the waitter thinks that you are ordering more food than you will be able to eat they advise you to stop ordering so you wont waist food and your money.
