The number of times I had been remoted into a user's system while they were "rebooting" is too damned high. Also, a lot of them got upset with me for then restarting their computer because they had unsaved work up.

Always fun to have that conversation with a supervisor, most of them don't like that their people wasted time and lost work because they were not following directions AFTER BEING TOLD TO SAVE YOUR SHIT AND REBOOT.
