They don't care about the foreigners who complain about 20 baht, they don't want them. What don't you get about this? You are a GUEST in their country. They don't even need to allow you to come here, yet they do. They could send you back to your home country if they wanted, yet you're allowed to live here. There's a reason people choose to live here over vietnam and cambodia and phillippines even though those are easier visa wise. Lol, you people are so entitled. You get to live in $100-200 a month apartments and eat food that costs $2-3 and then you complain about dual pricing at national parks. How about you go back to your country and pay $1k+ per month for rent and $15+ for a meal at a restaurant instead?
