I worked for a manager that told everyone he was an aircraft fitter in the UK, we needed to get some rotors machined. I didn't measure them as it was nearly a new car and I'd machined so many of them at my previous job I could tell by eye when they were close to being at maximum wear. I blonk them onto the table to be carted away for machining, 10mins he comes back in cussing and carrying on like a porkchop that they're undersize. I measure them in front of him and he goes, "see they're undersize" I look at him like a fuckwit in despair after he abused me and tell him "you better ring the owner of this shop up because I'll be resigning in two weeks time".The newly discovered 5th way to measure with venier calipers.
He was a true clown, he used this part of the callipers to take his measurement.
