Remote server software installation support is great!
You can watch them trying to understand where what is on the file system, they repeatedly switch between windows without doing something on either of them and they set your IE browser policy to allow all kinds of domains & sites which are preventing them from downloading their software.
Todays guy did not know how to transfer a file between the local machine and one in remotedesktop. 😄

(If you do support like this, then don't get me wrong, I'm not making fun of you personally, it is just funny to watch if you have to actually sit there and wait for the support to finish.) 😉
