I would say when i fixed something catestrophic "whose your daddy!" then
one employee said IT Daddy; i said yeah! whoseyou IT Daddy!??
you are robert they said! and thats how my BIG fat ego started.
I can understand that. If it is your own system, you can afford to do that. But if you have hundreds of sales people who can't do their job, every minute counts. If it can take you 2 hours to restore a system, you don't want to spend 4 hours figuring out what went wrong and how to fix it.
