is right – my bank is a member of the wunch! I’ve just seen that they’re charging 3.5% on any cash withdrawal here, even though I’m in credit. Er, is it that much more work to spew cash out of an ATM here rather than in the UK?

Mastercard charges the larger of 2% or 2UK pounds for cash withdrawals and (from comparison of a mastercard purchase with a cash withdrawal from my bank on the same day) appears to give a marginally better exchange rate.
