No April Fool joke!

How to 'cook', not one, but two VISA cards at the same time. Simple. Make sure that you have both cards in your handbag for safe keeping just before you comfort your husband as he begins to undergo his electro-magnetic resonance treatment in one of those wretched claustrophobic tunnels. After prising Marion and her handbag off the side of the machine we discovered the next day that both cards are now null and void. We are almost too scared to try the American Express cards! Too late the AmX cards are also cooked - we found out today in Lima. Subsequent calls to a Mildura financial institution seems to have brought things under control. The moral of the story is stay well away from those electro-magnetic monsters, or leave your cards at home!
