Me too. And the banks will collude: "I'm sorry sir, our cards are entirely secure against fraud, so you must have agreed to that transaction.  After all you admit you were in the Streatham Hill Spearmint Rhino Gentlemen's Club on that date. If you prefer, we can check that with your wife ..."

I agree - and one can think of many variations on it. The ethics are similar to the procedure whereby insurance or utility companies set up "continuous credit card authorities" on the basis of your presumed consent to some 3pt type deep in the bowels of their web site, and if you protest they say "But it's there on the T&Cs page ...
