So this shit happened today...

We were asked to implement a functionality on the device that allows it to go to standby mode to save battery power. Once the device enters that state, it can only be woken up by actual bus-network activity, and usually that means connecting a shit-ton of wiring harness and network emulation devices... Before implementing and releasing the device software that does this, we told that fucktard customer how difficult it would be for him to connect to the device without such a setup. He seemed to be fine with it and said rather arrogantly that we should implement the requirement as asked...

Well okay you cock-sucking motherfucker, you'll get exactly what you asked for... We implement the functionality and deliver the software...

Now this pile of shit comes back running his mouth on how the device tears down all its interfaces (to reduce power consumption) and he can't connect to the device anymore.... Well what else were you expecting you dickhead.
To make things worse for me apparently he runs to the manager describing his apparent problem. Both of them come to my desk.. With that fucking Bastard hiding his smugly mug behind the manager's back... He thought he was going to have the upper hand... Well guess what fucked piece of shit, I came prepared... I showed the manager how this was a part of the requirements by throwing that JIRA ID in their faces... The manager seems to understand but this relentless fuck wanted me to implement a "workaround" that would allow him to connect to the device easily... The manager almost had me implement that workaround, when I expose a huge security flaw in doing so. Guess what, now the entire team comes to my desk and start supporting my statement... To make it better they also tell how doing so will violate other requirements...

I've never felt so happy in my entire fucking career, when the entire team stood by me and watched that asshole drag his sorry ass back to his place
