I’d nearly forgotten to post how the story with the mobile phone ended. Actually, everything turned out just fine. I arrived at the agreed meeting place at 8:30 p.m., not really knowing what to expect. But then I saw the man with the metal detector, systematically sweeping the beach for lost goodies. As I approached, he looked up and with a friendly smile fished my phone out of his bag, and handed it back to me. Although we couldn’t really communicate (he didn’t speak English or Spanish), I got the idea he was a very friendly person. I gave him a small tip for taking care of the phone.
So, all ended well, and I’ve got my phone back.
