we once hired a new technician who never stopped talking about his qualifications, his training abroad (U.K, im south african), his electronics repair business et al.
he was given a board with a faulty supply (7805), he managed to repair the board and had an accident with a side-cutter, he managed to break a ceramic cap in half, poor guy panicked, looked around his tool case for a solution, and decided that super glue would the patch up the cap just fine
. when asked why would he do such a thing he told the manager that super-glue won't affect the working of the cap
