Sitting in a bar with a senior colleague (Me - Student part timer, Him - 15+ Years of experience).
We started talking about our projects and he mentioned that after this, he'd get to spend his evening fixing a git merge, which went wrong because one of his teammates used cherry pick and thus messed up the history a bit (oversimplified).
So he tells me he'd be spending hours to get an overview of his colleagues codes (multiple devs and only team leader knows who does what exactly).
So I suggested he revert these cherry picked commits and so could maybe solve the problem in less time.
He thought about it... Told me HE didn't think of that and thanked me for my help.

Long story short: Today was a good day :3
