I love it when people spout the myth about Welshies speaking Welsh only when an Englishhman walks in. I will admit that, when I arrived at Valley in 2002, I thought exactly the same (I am English through and through). Then I met and married a Welsh girl and I can assure you that they speak Welsh for no ones benefit but their own. It's their language you see. Would you say the same if you were in France and you heard the locals speaking French?!
The worst people in North Wales are all the visiting Scousers and Mancs but let's not go down that particular rabbit hole.
