Oh, back to the OP.
1. People who don’t read manuals.
More specifically, the type of supercilious **** who appears to take pride in the fact that they have bought a nice piece of tech and have absolutely no idea of how it works or it’s capabilities.
2. People who post on HiFi threads who have obviously never, ever used their ears.
3. People who own a nice BBQ but are incapable of cooking anything properly.
4. Tories who keep telling me that they had no idea BJ was a mendacious, priapic alcoholic with the morals of Jeffrey Archer.
