A recent Slashdot article claims that the markup on the new iPhone X is way too much.

Be that as it may, this comment from a reader made my day as it is so true:

A Plumber Goes on a Call to Fix a Leaky Faucet...

When he arrives at the customer's house, he inspects the faucet, installs a new rubber gasket, and gives the customer a bill for $100.

"This is outrageous," says the customer. "I demand an itemized bill."

The plumber quickly writes up an itemized bill:

Rubber Gasket: $0.50

Knowing where to put it: $99.50
