Today I watched a conversation between the electrician and the chief who had already fainted this morning:

Fingers, don’t get started! If you want to know, electricists should generally drink before working on safety techniques.
Chief : What? Have you drunk your brain?? to
Electrician (opening the technique for TB): See, black on white is written: "Before working in current electrical installations with a voltage up to 1000 volts it is necessary to remove the voltage".
The intended strict complaint was cancelled, limited to an oral warning)))
