You are right, endlessdream. However, it is true that if you look like a tourist some people and even in official government prices change. For example, a local can buy a ticket to a performance at the Gran Teatro for 30CUP, while the same ticket costs 30CUC to tourists. Just like everywhere else in the world, it helps to blend in. However, my point with my story was that I didn't have to blend in. By virtue of the way I looked and the fact that I speak Spanish, I blended in even without trying to.
