I’ve just got a new battery in my Mickey Mouse watch.

The first place I tried couldn’t do it. They looked at the watch and told me it would cost �9.99 because I needed a lithium battery. A minute later they said that the watch would not be water resistant after they finished. Another minute after that they told me that they couldn’t get the back off the watch because it was unusually large. When I asked if they knew anyone else who could open it, they suggested another shop but added “our tool isn’t big enough, and we all use the same tool, so he probably won’t be able to open it either”.

So, I visited the other shop and, sure enough, he had exactly the same tool, but he had no problem opening the watch. For �4.50 he had the new battery fitted and the cover replaced in less than a minute, proving beyond a doubt that the size of your tool doesn’t matter; it’s what you do with it that counts.
