From Warren Kinsella. My favorite:

Public Servants Rule: This is a true story. When I was in government, I would make every new political staffer follow me outside my office door. I would introduce them to all of the secretaries, and the mail delivery people, and the receptionists. “This is the public service,” I would say. “These people have more power than you, because they were here before you, and they will be here long after you are gone. They do good work. Be nice to them.” In the current circumstances, that also means not going on national television to accuse public servants of crimes, destroying their lives in the process. It’s not fair. They cannot defend themselves in the manner, say, politicians can. And remember this: public servants don’t say much, but they always, always have the last word.
