I've not worked in tech support exactly, but dev on internal apps that we also run the ops for.

These types of users beyond the morals/niceness issue just seem plain stupid.

The most intelligent manipulative users I observed were the ones who do the exact opposite - chew out the boss regularly, but are absolute saints to the lower level "doers".

They engender good will with the people actually doing the ops work, often end up getting them to go the extra mile. Plus they shell shock the boss enough that the ops people are given the priority to work on their issues.
