They know what's best. And if they don't know what's best, they'll make a form that lets you specify what's best in a way that is so confusing that afterwards you don't know what's best anymore, either. This way, they can misunderstand what's best and do something nobody wants while blaming you for wanting it. If you don't want that, you need to tell it to the right person, and if you don't know the right person you can ask whoever you think is the right person who will then point you to someone who is certainly not the right person but might point you to someone else until you find out that YOU were the person you were looking for all along! Now that everyone is happy you found out what you wanted to know, they can get back to doing the thing you didn't want them to do.

Panel 1:
P is explaining something to H on the whiteboard.
P: So, ... in your thesis you’ve looked at functions like this ...
H: Oh no! Stop! That is a permanent marker!
Panel 2:
P: sigh ... that’s fine. You see, the administration decided scientists shouldn’t waste time buying whiteboard markers anymore. There’s now an official whiteboard marker requirements form, a quality control survey and you must get whiteboard sustainability training. I spent one whole week on this last month.
Panel 3:
P: Anyway, long story short, you can erase permanent marker decently well with nail polish remover. I have to buy the nail polish remover myself, but at least I can use the whiteboard again.
