My friend used to be a restaurant consultant. He told people “Don’t do it. That’ll be 100 grand, please.”
A favorite old joke: A mechanic (or plumber, or other workman) comes out. He listens to the malfunctioning machine, then reaches down to his tool belt and pulls a hammer. Three taps, and the machine is back to normal.
The mechanic then presents the client with a bill for $50. The client is indignant. “I’m not paying you fifty bucks! You just tapped it three times with a hammer! You’ve got a lot of gall, asking fifty bucks for that!!!”
The mechanic calmly nods, takes back the invoice, and hands it back to the client. The revised version reads:
TAPS WITH A HAMMER: 3 @ $0.25
KNOWING WHAT TO TAP: $49.25
