Read this carefully!!!
This is what I started doing a few years ago and so far it has worked like a charm.
When entering the DR, the "aduana" inpectors are supposed to speak english so when they ask me (in inglish or spanish) "dejame algo para la cerveza/leave me something for the beer", I tell them: "I don't have any money right now because this is an emergency trip, but since my friend came to pick me up and he has some money with him, please write your name and badge number and I will make sure to send you some money right away". They will automatically say "no, it's ok, bye" because they feel that you will report them to their supervisor!!. I do the same when leaving the coutry but at that time I tell them that I would call my friend on the cell phone and he would send him/her some money right away. Works all the time!.
Better yet, befriend an inpector. That's what I did on my next to last trip. I befriended a woman inspector and within 3 minutes, with my charm, I had her whole schedule, home phone home and cell number. On my last trip, I called her by her name, she left her post, gave me a hug like we were old friends, went back to her post, asked me why I did not called her, stamped my passport, left her post and went with me to the gate and stayed with me for almost an hour!. She did asked me for something, she asked me if I was related to so and so person and when I answered "yes", she told me that we would be friends for ever as long as I told that so and so person that she was nice to me!. Now, whenever I go to SD, I call her and she tells me when she will be on and to look for her. Now, that what we call "turning the table"!!!!
