I was wondering, say I got a handpay whilst in Vegas (wishful thinking I know :evillaugh). From what I understand UK citizens arn't liable to have tax's taken off the winnings. However, what I want to know is what proof of your citizenship the person giving the handpay will need to see? Will it have to be a passport or will a UK driving licence do the trick (it is a provisional licence mind you)? It's just that as we all know bringing a passport around with you everywhere you go isn't the safest or wisest idea (I don't wanna have to head to the British Embassy after losing it whilst drunk, haha). I have an old passport that I could bring around just in case lady luck is on my side! I look forward to hearing thoughts of Brits and others with more knowledge than me, cheers!
