Used him twice - he tried to con us both times.
The 2nd time was only because we needed a small amount of cash, banks were closed & didn't have card on us.
I made sure he gave us the rate on the board NOT the much lesser exchange rate he tried to. 'It's just pennies, it makes no difference'!!
We avoid & use Nationwide & Finansbank.
He's got make a fortune in cons from Tourists who are not members of this forum.
If you do use him - make sure YOU count your cash after he's handed it to you, in front of him - don't just let him count it as he's good at sleight of hand.
Catch him out & you will get the money he owes you with a smile. I reckon many don't bother counting it, after seeing him count it in front of them & walk out short.
