One of my favourite clients was an engineering firm. I once wrote a letter of intent for them concerning the purchase of a business. They only had one comment on my draft document. They asked me why I had only taken the numbers to two decimal places, which is not a surprising question coming from a group of engineers. However, I found the question to be quite amusing, since the numbers in question were dollars, where the use of two decimal places is quite an accepted custom. (Did you ever have a store clerk say, “that will be $5.0156?). But at least they read the document, which is more than I can say about many of my other clients.
