Wow, honestly? That blue shade story is what got me too. I can't believe someone actually made them go through that many revisions over a color you could barely tell apart in the first place. That's just absurd. It makes you wonder if they were even paying attention to what they approved before asking for changes. In my experience, clients like that are usually just trying to justify their own insecurity about the choice, but still, that is next level frustrating. Your mileage may vary, but I'd have lost my cool after the third or fourth tweak to that blue.

Bet on humans being the weak link every time and train for that.

Got a buddy who spent an entire Saturday rebuilding his entire home lab setup because a single underscore in a TXT record broke his email. He didn't catch it until his wife asked why all the server racks were pulled out on the living room floor.
