Sorry to say that Thai ladies do not have the best reputation in EU and UK.
I saw a program on TV last year that showed live footage of what they get up to, especially in London. A friend of my brother recently married a Thai lady and needless to say he was the laughing stock of his mates. Very unkind , yes, but a lot have blokes have been to Thailand , and none can say that the prostitution is not in your face and cannot be ignored. Thailand does not have the best reputation abroad.
