8. Make a proper donation in the donativo albergues, if you can afford it pay what you would for the same service in a private albergue.
9. Educate yourself on the signs of bedbugs, and if you see them, don't scream and shout, but have a quiet word with the hospitalero.
10. Live a little in each town, so you appreciate them as unique places. Even if your feet are hurting and you are tired, go to the little museum, climb up the city walls, or go swimming.
11. In cities, support small family run shops wherever you can (look for a small sports shop before bussing out to Decathlon).
12. Make a point of saying Good Day to elderly locals in the villages, and stopping for a chat if you speak Spanish. Many of them have their family living far away.
13. Take an interest in what is in the news in Spain. Notice how stories about your home country are reported.
14. If it's not in your culture, practice kissing people on both cheeks before you go, so you don't flinch when Spanish people do it to you.
