They do this in Thailand. When you live here & don’t pull in the same income as before but can speak the language & whatnot, it feels awful to be treated as such an other when your local community accepts you. You also need to understand how they check which is normally just a skin color check—I’ve spoken to Filipinos that never get the foreigner rate. The worst one for me was in Laos where I was joking in Lao with the staff & had to pay the price, but some ethnic Lao folks from France got the local price despite not speaking a lick & asking me local culture questions in English. I didn’t hold it against them personally, but it really sucks.
