Random Yet Strangely Interesting Conversation Of The Day

In the carpet shop, buying carpet (no, really?) for the new house, the carpet salesman and I had this conversation:

Me, pointing at horrible flowery carpet samples: Who on earth buys those?
Him: The further north you go, the more patterned carpets are sold.
Me: Is that true?
Him: Yes. It's a well known fact in the carpet industry.
Me: Really? But why?
Him, sagely: Just think of Blackpool landladies.
