When I was a kid and full of enthusiasm for Legos, I bought a very small pirate set---a rowboat, a canon, a pirate and a soldier---with money I'd earned, because my friend had a larger set with the canon, and it fired a piece via a spring mechanism. To my great disappointment, Lego had changed the design and the canon wasn't functional. I wrote them a letter (pen and paper, back before the Internet), and when they replied it was legal-speak about liability concerns if the small piece ended up in someone's eye.

On top of my disappointment, they criticized me for having written "Legos" and told me that their products should be called Lego bricks or Lego toys... great way to give an elementary-aged boy a poor impression of Lego's customer relations.
