That is kinda cool but sad also. I knew someone like that as well. Worked for a company were the best quality control person for boards was a functioning alcoholic. And I mean like her hands started shaking around 9 o’clock. She would drink all day long from tiny schnaps bottles hiding in her office or from her flask.
These boards were mostly for prototypes or small series, so always something new to look out for. Tiny parts mounted by hand. She would catch any error or faulty joint. But couldn’t talk straight. I never understood how that’s possible. I guess these people are better focused when drunk/high. Or just ultra pros at their jobs…
