In 2009, I went w a friend who had an "interlude" on the beach w some guy she met late at night. She couldn't find her purse and camera afterwards. Sure enough, both turned up at the airport the next day. The following year, same friend lost her purse and passport again, and the hotel we were at got a phone call from whoever found it. And again, another friend once got super wasted at Shellona, and lost her purse and phone. That also was returned, I forgot the exact detail, but she got it back.
Moral of the story: My friends drink too much. (truth is, I don't travel with either of those people any more. But I hope for the people whose friends do, they find whatever they're looking for, and don't get too b!tchy with the friend who is spending their vacation driving around the island looking for their lost belongings.)
