Not sure if this is the right place but hoping someone in the industry might be able to cast some light on an issue I have. I was in the USA recently and won a little bit of money in Las Vegas. I have now taken $1000 USD to Western Union to convert into NZD. I gave my NZ drivers licence and a bank statement with proof of address and they said they couldn't exchange it without me providing proof of funds. How do you prove a slot machine paid you out? I asked to see what their requirements actually were for proof of find and it was US wages or salary, sale of a house or inheritance. How can anyone prove funds on this basis unless of course you buy your usd grin the same place you convert but even then how would I explain I purchased $200 and won $1000 and now want to exchange $1200.
