And last week I had a Debit Card transaction "declined", when what they 
meant was "we can't seem to contact your bank at the moment, so hard 

But I suppose they'd say it was the POS machine declining to take the 
card, not the bank declining to authorise the funds. They really should 
have two different expressions for that.
