A colleague came to me, telling me, that "my special trick is not working for him".

So, I asked him to show me his entire process. He showed me only the last step.

Ok... here's the thing. I used to think that non-it people had brain damage when it came to communication of simple thoughts. But, when a senior tester cannot follow a simple instruction in an environment that he fully understands, then we have an unidentified issue.
