One inappropriate experience I can think of is during an internship at a multinational company that made networking and electrical components. My mandate was to do an analysis on the electrical performance of the company's products versus the competitors. It took me something close four months to measure, to compile data, do an analysis and create a report.

Then came the time to show the results to the engineering director. Let's say the news were not good, so I figured people should have their hears opened. Anyways, my supervisor and I made a presentation to abstract the main points so the information was not too difficult to process.

10 minutes into the presentation, the director of engineering just fell asleep and was snoring quite loudly. I asked my supervisor "should we wake him up?" and so we did. When he woke up, he asked us to wrap it up and pretty much gave no fucks about the results or the presentation. Nobody really cared about the results after that. Talk about wasted time lol.

Luckily I don't work at this shithole of a company today.
