Single responsibility Memes

Someone's had enough of the 3000-line function that calculates tax, sends emails, updates databases, and makes coffee all in one go. Nothing says "I've reached my breaking point" like passive-aggressive office notes taped to the wall. Single responsibility principle isn't just good practice—it's apparently grounds for workplace violence if ignored. The colleague who wrote this has definitely muttered "what the hell does this even do?" while scrolling through functions named 'processData' at 2 AM.

That sign is basically legacy code in a nutshell. Some engineer 15 years ago decided to save 20 bucks by wiring the light switch to the elevator control system, and now we're all hostages to their terrible architecture decisions. This is exactly why we preach separation of concerns. Your light switch should do ONE thing. When a junior dev asks "why can't I just add this feature to the authentication service?" show them this picture and watch their soul leave their body.
