Balmer,
It's not just credit card fraud they're afraid of (and the scale of that problem is huge). They're also concerned about funds getting diverted to terrorist organizations.
For what it's worth, Andrew and I have a joint Barclay's account. I periodically receive checks from the SAME POLICE organizations in the States for freelance work, checks from the same organizations I've worked for the four-and-a-half years I've been here, and each time, it takes the check up to six weeks to clear. It's maddening. Barclay's has variously claimed that it takes that long to verify that the funds are there (uh, are they using sailboats to cross the Atlantic, and then the Pony Express by land--do they not have computers here to electronically verify funds?), that the problem isn't on the UK side but on the US side, etc. Regardless, it's BS. And there's no getting around it, because all the banks are the same here. Andrew is amazed that I actually could SPEAK to my local Chevy Chase bank manager in the States, as it seems impossible to speak to a human being here unless you go to the bank, which inevitably entails a polite but useless conversation with a teller: "I'm so sorry (look of helpless comiseration), there's just nothing I can do." That's the can-do customer-service spirit one grows to love here!. And they don't provide phone numbers to individual branches, probably because a) they don't exist, or b) everyone's continuously on a tea break and won't answer the phone anyway.
