I know that some people get upset when they have a question, and they don't get the answer but some suggestions. But sometimes, people are not aware of the alternatives, and it's important to remind them that perhaps a better solution exists.

If someone asks how to cut crusty bread with a butter knife safely, you can talk about the proper technic, how most people do it wrong, write a book about your industry do it better, but perhaps, someone should also mention that it's easier and better with a bread knife.
