I tend to be very forgiving when I find stupid bugs in code. 

I deal a lot with vendor supplied apps in my current position. As a developer with a QA background, I tend to find a lot of things wrong with their code.

While managers are freaking out calling for heads to role, and demanding to know who didn't do their job, and vendors are attempting to deny there is a bug and explain how its user error.... I generally just like to point out that there is a bug and ask that it be fixed.

The strangest of events can align to cause bugs, this story demonstrates why.
