I agree. Add too much salt to the food and people will say that you've ruined it. Some people won't notice it because they are less sensitive or for other reasons but the food, for some, is ruined.

This happens a lot with the software development where one simple bug in your application makes the user say that "it doesn't work". We, as developers, tend to get mad when all our work is deemed unfunctional because of a simple error but we usually don't see that it is a "simple error" only from our perspective.
