You are in your car, reading the menu, in the drive-thru lane at McDonald's.
Then a voice appears-May I take you order please?
With confidence and without a hesitation you reply -I’ll have a number 5.
The voice says-proceed to the next window please!
You pay the 5 bucks at the first window and proceed to the next window
And… there it is, in a neat package-the value meal that you just ordered. And that makes you very happy!
