My brother often does things for me that are out of his way. I do thank him of course. But I got to thinking. "Do I need to verbally thank him? He should know that I am always appreciative when he does something for me." But then my thoughts rolled on and I got to thinking that when you stop saying thanks to someone for doing something for you, even though you actually are thankful, they may start to feel that what they are doing for you is expected. I'm sure that people would rather do things because they want to, and not because it's expected. That's what we call being taken for granted. Now every time my family or anyone else does something for me that is out of their way, I will call them again to say thank you even after I thanked them when the incident originally occurred.
Now back to my original point. Yes, the person is just doing their job, so why say thanks to them? Not only is it polite, but it may also get them out of the "'I'm just doing my job, I'm just doing what's expected" mentality. I'm not talking about saying the "just polite, not looking in the eye thank you." But actually look them in the eye, nod, and say thanks. If they catch it, I'm sure they'll be happier and who knows, maybe they'll actually enjoy being at work more and start performing better? Who doesn't like being appreciated? And all it may take, is a little thank you.
