A Canadian guy at my hostel here in Bangkok lost his wallet last night so is without cash and cards. He flies back to Canada later today but needs some money to survive on and pay the hostel bill.
He called the Visa emergency number and I was surprised to hear that they cannot get him emergency money today. I have used this service in the past in more difficult places than Thailand but I guess things have changed.
There are Western Union offices or agents nearby and he has PayPal. But Googling for the two in combination I learn that Western union does not support PayPal at this time and, worse, there are some scams around involving the pair.
He also asked at the hostel if he could pay his bill using PayPal and transfer some extra money that they might be able to give him in cash - but apparently it's not possible.
