Obviously I can´t speculate what this fellow was doing in this particular neighborhood, but most of the foreigners in that part of town are `tricks,` using economic power to sexually exploit young females. I´m sure it gets annoying, especially to a little girl who has to live in that environment, and whom I have no doubt has seen more than her share of extremely repulsive foreigners on their worst behavior in that part of town. I know for sure her behavior would have been seriously frowned upon in the Thai boonies where I spent about a year. See, tricks, well, they get treated like tricks. Doesn't matter if it´s Thailand, New York or Timbuktu. When your 18 year old sister, or your friend's sister is getting banged on a daily basis by grossly overweight and supremely unattractive septuagenarians pumped up on too much alcohol and Viagra, and waving around way too much money, you become intimately familiar with the attitude known as contempt.
