I noticed this pattern, in Central Pattaya near shopping areas there is some strange people, looking Indian or something similar. They come to random people trying to give some weird advice, usually they start without any manners telling that you are too fat, skinny, bald or something other about person's appearance and say they have advice, stupid and annoying. I smell it's some scam going on or just thieves trying to distract victim. Maybe someone smarter can comment what it's all about?
