Who told you that. I have lived in Thailand for 21 years and still have a UK bank account.Get proper advice from a lawyer when you come to Thailand and nobody else
Im in Doha now and its around mid 40s everyday. high humidity. Uber taxis are good and easy. its too hot to walk about daytime. but there are a few very nice malls. nightime. i would go to bars in the big hotels. Its not cheap here but worth a day or 2 if you have never been here before.
