Hi-Tech Guy..Too Good

Once upon a time there was a shepherd looking after hissheep on the side of a deserted road.
Suddenly a brand new Porsche screeches to a halt. Thedriver, a man dressed in an Armani suit, Cerutti shoes, Ray-Ban sunglasses,TAG-Heuer wrist-watch, and a Pierre Cardin tie, gets out and asks the Shepherd:
"If I can tell you how many sheep you have, will you give me one of them?"The shepherd looks at the young man, and then looks at thelarge flock of grazing sheep and replies:"Okay. "
The young man parks the car,connects his laptop to themobile-fax,enters a NASA Webster, scans the ground using his GPS, opens a database and 60 Excel tables filled withlogarithms and pivot tables, then printsout a 10 page report on his high-tech mini-printer.
He turns to the shepherd and says, "You have exactly1,586 sheep here."
The shepherd cheers,"That' s correct, you can haveyour sheep." The young man makes his pick and puts it in the back of his Porsche.
The shepherd looks at him and asks: "If I guess your profession, will youreturn my animal to me?" The young man answers,"Yes, why not."
The shepherd says, "You are a Management Consultantfrom a top-notch consultancy like McKinsey,etc. .".
How did you know?" asks the surprised young man."Very simple," answers the shepherd.
"First, you came here without being called.Second, you charged me a fee to tell me something I already knew. And third, you don't understand anything about my business...Now can I have my DOG back, please?"
