What is something that absolutely pisses you off?

At my current job


There have been several times where I had the right intentions in doing something. However there were a handful of times where I was reprimanded because I didn’t do something the way it was done for years despite the fact I noticed the imperfections of the process and then made adjustments to make it more efficient.


Meanwhile I have seen co workers do things that are completely against the rules and nothing happens to them.
