You're an accident waiting to happen.
After your initial posts about buying weed here and all the warnings you got, you still went ahead.
Whether the chica is playing you is the least of your problems.
Here's a scenario for you.....
I was talking to a DNCD agent (Dominican version of DEA) a few days ago, and she was telling me that biz was slow, that she hadn't had a bust in a 1 1/2 years, so she spends most of her days dicking around on the computer.
All of a sudden, she happens upon your post.

Bingo.. she just hit the jackpot.
A quick check at Casa Linda for the names of the dudes who stayed there on those particular dates, and now she puts your names into the immigration computer, so as to know when you next visit and where you are going, and it matters little if you do any dope the next time, she'll still bust you and finally be able to afford that Mitsubishi Montero she's had her eye on.
