Dear person with a PhD:
The fact that you went to school for a long time and wrote some sort of thesis on something that almost no one else in the world cares about does not impress me. You are not glorified in my eyes. Have and use some common sense. Act like a human being. Pay attention to the details of life and appreciate those who end up stuck trying to help you and then we'll talk. Until then, the god-complex only irritates me and makes me want to stab you with a pencil; not help you find the best deal on the most perfect piece of technology to go in your office/lab/whatever.
