Yeah. I got told to put in a caching for a system that made very slow calls through a handful of proxies to the other side of the world and back. We went with redis for the "PoC". I'd tried explaining that if a query is only made once every 24 hours and the data can't be cached longer than that because it's considered too out of date then a cache is pointless extra complexity. He wasn't having it though, so he made us build it and demo it to a room full of people. Fortunately the room understood the simple explanation and he listened to them where he wouldn't listen to the dev team, so a few weeks of work was scrapped there and then.
