Best advice to people needing to change money: Don't use anyone who approaches you asking if you want to change money, don't change money in a clothes shop, walk a few metres more and use one of the change shops or banks.
I too had no need to change money in the 5 years I was there and throughout that five years he never gave up asking. I think I totally ignored him for the last 4 and a half years and STILL he asked.
