How Not to Look Like a Tourist
It’s not just the inability to speak Spanish that marks one as a tourist, as there are expatriates who have acclimated quite well to the culture without ever progressing beyond basic greetings like buenos días and ¿cómo está usted?
Visitors tend to be substantially less modest in terms of clothing. No local, for example, would walk into a restaurant or boutique in their beach bikini or barechested in a pair of board shorts. A little modesty goes a long way in establishing local bona fides.
