Mine is that I worked for a company doing engineering and designing machines. I have a degree for this compared to my boss who only took a 6 week course in my field but I was getting paid decently so I can pretend to play dumb. The man hired me to create 3D designs from 2D blueprints and when I printed my work he would complain about the 3rd dimension shows and wanted to “look at it straight on”. After my 4th attempt of trying to make a flat drawing out of a 3d object. He proceeded to not let me do my job anymore.
