IT enemy No. 5: The Freeloader
If you know anything about technology, you've surely encountered this time- and patience-sapping foe. A "simple" question about computers morphs into demands for free 24/7 tech help when you have actual paying customers to support.
Recognizing the enemy: When they find out what you do for a living they immediately (a) ask for your card, (b) start flirting shamelessly, or (c) launch into a tale of technical woe.
Your best defense: If possible, retreat. When you spot a user like this just start running down the hall screaming. Unfortunately, since you're often related to these people, you will eventually run into them at weddings and funerals.
