So, I get a call from the parents-in-law last night. They've been robbed on holiday, running very short of money, very bad situation.
At one time, there was a simple solution to this. You found a branch of Western Union, handed over some money and gave a code and password, and someone collected it at the other end.
Nowadays? Can't do it. Money laundering laws and all that, and basically about drug money. You need to show some ID. Oh, but parents-in-law also had their passports robbed too.
It might be a small cost, but next time someone weighs up the pros and cons of the War on Drugs, it's yet another thing to add on the "cons" side.
