I Report Bugs - Do You?

I received an email telling me that my blog was having problems (showing code all over the page). I quickly checked and didn't see a problem and sent an email back. The response I received was:

Your blog looks fine now. Sorry for wasting your time.

What a misconception. The person had taken the time to report a possible bug on my site. In my mind they are doing me a huge favor.

Most of the time I report bugs. And this extends beyond the online world. If I'm at a restaurant, I will try to tell the manager about an issue - most of the time not to fix it, just to make them aware. Of course, you always evaluate how easy it is to report the issue. If the manager is not around or there's no contact mechanism on the site, then I don't report it.

Generally, people are appreciative of the bug report. But it's sometimes surprising the response you get. It's almost that you are bothering them. They don't want to hear it. No wonder the person was so sensitive about "wasting my time."

So this made me wonder ... is this the norm? Do you report bugs? How do you decide if you spend the time? And, what's your feeling about how they are treated when you report them?
