Dear New Department Head:

We just can't beleve that you would announce that you're contracting for three full days of training for the whole department in something we've been doing for years. AND before you even tried to obtain approval for the expenditure! What an insult - you come in and "Hmmm, I don't know anything about these people so they must not know anything." So we'll be happy to demonstrate that percieved ignorance to you the next time you ask for information.
