I told you fucking moron clients doing that "little" change would be complicated and in the worst case it would end fucking up your whole spaghetti crap. A really HUGE spaghetti monster of that you aren't aware because you guys don't know a shit about coding conventions.

*Clients call me complaining about their software is broken*

-Hey, we're in serious trouble. Our users aren't being able to see the proper calculated values. Why that little change had so much side effects?
- I already told you why.
- Can you fix it asap? Our clients are complaining.
- No. Deploy an old copy of the affected modules while you give me a prudent time to refactorize that crap.
- Refactorize?
- ...

I used to work in their place, 3 years later I quit that crappy job and decided to make them my clients. I escaped from the micromanaging thing but I didn't from their ugly practices.

Anyways, I have to fix this shit asap. Money talks, at least until I can find a better client.
