Apparently, Argos are required by law to take the name and address of anybody purchasing a TV or any TV related peripherals and pass these on to the licencing authorities. The lady in question was having none of this and contested the issue even after the store manager was called. She claimed that, on principle, it was wrong that she had to supply her personal details and if she wanted to buy a lawnmower, these would not be required.
In the end she stormed out without making a purchase and Argos lost the sale of a 500 TV.
I can't help feeling she had a point :-)
