Your original behavior lies in treating a janitor and not how you treat your CEO or someone in a higher position. It is not recommended to hit words at people, rather try explaining them using better words, and there is a certain way of communicating your thoughts. If you pose a very fake attitude in front of them and start speaking ill about them once they leave the place, it is never a good sign of treating another human. If you have a very terrible habit of speaking about people behind their back and don't have the guts to say it right on their faces, then you have repulsive behavior.
There are certain self-check parameters you can assess to understand your ugliness quotient.
