unfortunately I'm Seldom in Bangkok 🤷♂️ TT would be a major player and they don't offer a better exchange rate for higher notes. But are generally very competitive with their rates. Strange comment how you can say others rates are rubbish without knowing. I find 0.05 of a baht not worth running around for 🤷♂️
I know superich do, and think they may be the only ones that do. I've never changed currency in Bangkok and I don't think super rich have anywhere beyond. I could be wrong. Though the difference is very little
