Firstly petrinemcshane let's get one popular misconception corrected. ​In England and Wales, only Bank of England notes and Royal Mint coins are considered legal tender. https://www.bankofengland.co.uk/explainers/what-is-legal-tender What you need to do is what millions of tourists do when they come to England and Wales and that it exchange their toy town Monopoly money into sterling. For information you can do this at any bank or post office. Currently the exchange rate is 1:1 but that will certainly change if Scottish independence goes ahead. Secondly you comment on the lady serving's accent is grossly racist. There are many Welsh people in Carmarthenshire who have very English sounding accents. Also I am not aware of any legal definition as to what is a Welsh person. I am not connected to the business but a frequently in there and see how welcoming and friendly the owners are even to grumpy miserable gits. I couldn't do their job. They are hard working and are very well thought of in the local community. I doubt you can say the same.
