I too am of the old school. I do the polite thing because of upbringing. That is what my parents taught me to do. In fact that is what my parents practiced.

Many years went by before I realized that I do this for all the reasons that you mentioned but... foremost, I do this because it is right. Once I got this thru my head it was easier to let the ungrateful go on about their business without comment.

Knowing that you are right, respectful, and polite in all things is satisfaction enough. Acknowledgement of those things is icing on the cake.
