It reminds me of a presentation I attended many years back where well known maritime companies presented some of their latest products. The rep of one such company was going about as to how well built their life rafts were and that the welds on the rafts carried with them a lifetime warrantee. An old toppie, a seasoned sailor, stood up and told the rep “Now you are in the middle of the Atlantic and the welds fail, who is going to claim up on the warrantee?”. The rep couldn’t answer him and all had a good laugh at the rep’s expense.
