Ex-thai Nationals And Thai Bank A/c

[Flummoxed]

As much of my money is now in my Thai Bank account, I often use the visa card to pay for goods and services while in the UK. Today, I used it at Tescos in Hertfordshire. The young lady on the till was Thai. When I produced my BKK Bank card, she looked very surprised. She exclaimed 'How you can have this, you England guy!' I explained that I spend much of my life in her homeland and that is why I have the account.

She is convinced that she cannot hold an account in Thailand because she has renounced her Thai citizenship and is a British passport holder (why she did this is beyond me, I'd have gladly swapped with her;-))

I don't want to give her the wrong advice next time I see her, so can you think of any reason why she would not be able to hold such an account? If I can, surely she can?!
