2 Lack of skills: these type of people believe in "pre-knowledge" they don't need to learn "it's so simple".
Just like a receptionist who does understand etiquette and it's principles.
3 Illiteracy: we all know that the money of illiterates end mostly with literates. Never employ an illiterate, if you don't to spend money on training.
