Re: ahh, floppy disks
I was horrified when I first encountered continental plugs/sockets with their piece of springy iron wire as the earth contact.
I did a trade show in Paris some years back. We paid a fairly hefty surcharge to have a 15A feed to the stall. I was less than impressed to find they hadn't fitted one - our kit required electricity.
I called the electrician, who confirmed that we did indeed have a 15A supply. I was buggered if I could find it, so I got him to come to the stand to show me where lay this mythical cable.
He pointed to a bit of bell wire sticking through the carpet...
