Thats mostly true but if you go there enough you automatically blend in. When i first went i stood out, after quarterly trips there for a year i somehow blended in without even trying. Honestly don't even know what i changed but nkw they can't tell and its great paying super cheap local prices. They even say it when its bill time lol..... He's a local..... Than bills up and sometimes i feel bad but that's the going rate. For example a BBBJ at a hot toc (hair cut place) is about 400-600k for a foreigner..... Its 280-350k for a local. At 350k it's about $22 bucks..... Shitty exchange rate at the moment.
