Here's my personal favourite example:

	You walk into a car dealership to buy a new car, because your old car
is too slow to drive on the freeway; you need something faster.

	The salesman shows you a great vehicle. He tells you all about how this
car is the pinnacle of automotive technology. It's got muscle. It's got
finesse. It's got tons of state of the art bells and whistles. Your
friends will be soooo jealous. Chicks will dig you. You have to have it.
You pay the man and have it delivered to you house.

	When it arrives, you can't figure out how to open the door. The front
windows are opaque, so you can't see inside.

You: "Hey, delivery guy. How do I open the door on this thing?".

Guy: "I'm not the delivery guy. I'm your driver."

You: "Huh? Look, I don't need a driver, OK? I'll drive it myself. So how
do I open the door?"

Driver: "I'm sorry sir, but I can't tell you that. It's secret car
company stuff. If I told you, then our competition might find out how we
do it, and we would lose our competitive advantage."

You: "Whatever. I need to get to work. Let's go."

	You get in the back seat, but there is an opaque barrier between you
and the front of the car.

Driver: "Just talk into the speaker on your left, sir, and I'll go where
you tell me to."

	You get out on the freeway, but you're only going 30 kph.

You: "What the hell is wrong with this thing? I thought this car was the
fastest thing on the road. Pick it up, why don't you?"

Driver: "I'm sorry sir. I don't really know how to make the car go
faster than 30 kph. This is a new model, and the company hasn't yet
taught us how to drive it fast. Check in with them next month. They're
always training new drivers, and they might have a replacement for you
by then."

You: "Well that's just great. Let's get off the freeway. Take a left on
Broadway, at the bottom of the off-ramp."

	You exit the freeway, but as you are turning left onto Broadway, your
car stalls in the intersection.

You: "Hey driver, WTF?"

Driver: "Sorry Sir, I seem t0 baeo ++_?+CFY^K$# ekbae."

	The driver stumbles out of the car and starts spazzing out on the
ground. After a couple of minutes he's OK and you get back on the road.
There's an uncomfortable silence in the car. You don't tell him to turn
left any more.

	Six months later, the company sends you a replacement driver.

Driver2: "Sorry it took so long sir. You see, there's not much call for
drivers who know the streets in this neighbourhood, or that speak your
language. Most of our clients speak Esperanto, and are over in the
business district. They have priority when drivers are trained."

	The new driver can reach 70kph and he turns left by turning right three
times, so things are looking up. Still, the salesman told you this baby
can go 300kph, and you want to see it happen. You go to the company HQ
to talk with someone.

	When you get there, the office is cleaned out, and there are eviction
notices plastered on the doors. Oh well, at least you still have a
driver. As long as the city doesn't alter the street layout in your
neighbourhood, he'll do just fine.
