There is nothing more fulfilling than working you ass off 2 days, learning a new technology, and getting it to finally work as per the requirements and then ...

getting told that the absolute cunt of a client forgot the release date, announced its release 2 days early and decided to casually ask why there is no app on the released URL (it's a tiny Agonizing Reality [AR] app meant as a gimmick on the invitation cards for an upcoming convention).
My boss told me, the thing I worked on is now being scrapped and will not be released.

Yes, I wish the clients could slowly die in agony by a tree growing out of their appendix. Nature shall reclaim their corpses and feed a happy pig which I would happily have a feast of. 🤗
