Really good ... small story, moral of the story is very important.
A new vacuum cleaner salesman knocked on the door on the first house of the street.
A tall lady answered the door.
Before she could speak, the enthusiastic salesman barged into the living
room and opened a big black plastic bag and poured all the cow droppings onto the carpet.
"Madam, if I could not clean this up with the use of this new powerful vacuum cleaner,
I will eat all this s...!" exclaimed the eager salesman.
Do you need chili sauce or ketchup with that" asked the lady.
The bewildered salesman asked, "Why, Madam?"
"We just moved in, & there's no electricity in the house!"
Moral: Gather all required information before working on any project...
