Unrequested expertise and the invoice nobody commissioned

You mention a problem. Before the sentence ends, a colleague who learned the topic yesterday begins delivering the definitive lecture.

Why this tiny offence gets expensive

Advice can be generous; certainty without context is mostly noise wearing a tie. The exhausting part is having to defend facts you never asked to debate.

Workplace nonsense becomes especially irritating because the calendar, hierarchy and job description give ordinary annoyances the confidence of official policy.

The completely unofficial accounting view

Petty Invoice values the offence at €30.00. The calculation is not economics, law or accounting; it is the ancient discipline of turning irritation into a number with two decimal places.

The charge description reads: Negative consultancy fee for confident advice supplied without request, context or purchase order.

Recommended administrative response

Send a negative consultancy invoice for advice received without purchase order.

The point is the contrast: a familiar little annoyance gets treated with the solemn paperwork of a finance department. The more disproportionate the bureaucracy, the better the joke.
