What is something people you encounter at your job say that makes you want to scream? (Job, person & quote)

I was working at a tool checkout in my shop for a while, and the sheer amount of ignorance and repetition blew me away.

People would come in, see signs stating things like "Don't throw your hazardous waste in this trash can!", and people would straight up ignore it. Things got so bad that we had to stop offering a trash can in our part of the shop.

A lot of people would also just repeat the same statements, day after day, week after week. For example, we have iPads that contain maintenance manuals. We have to update those manuals every week, on the same day. Without fail, the same people always forget which day Update Day is, and have to ask.

The worst ones happen when people come to turn in their gear before end of shift. Most people are fine, but every toolbox has to be thoroughly inspected before being scanned back in. Often, somebody misplaced a tool, left garbage in the box somewhere, or there's some other undocumented discrepancy.

Most people are cool about it, and willing to make things right. But, some people act like you've purposely screwed them over, or react with total apathy and disrespect. I don't make the rules, man, I'm just trying to do my job.
