Charlie. Societies work best when there is a high level of trust. We have found that in Spain. You almost never pay right away when you get a coffee or food at a bar. They let you sit there as long as you want even if you are outside and they are inside. When you are ready to leave, you seek them out to pay and you sometimes have to remind them what you had in a busy place.
We have pretty much stopped asking the price of anything. Everything is about what you expect it to be, or less. Some things are amazingly cheap.
At hotels and albergues some pilgrims leave their backpacks in the hall or out front for the transfer services to pick them up. Then they are left out again at the destination. We often see packs or suitcases sitting unattended. We have never heard of a problem either in a book or from other pilgrims. If there was a theft you would hear about it. Stories like that travel fast among pilgrims.
