A new vacuum cleaner salesman knocked on the door on the first house of the street.
A tall lady open 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 in the next 10 mins, I will EAT all this dung!"
Exclaimed the eager salesman.
"Do you need chilly sauce or ketchup with that" asked the lady.
The bewildered salesman asked, "Why, madam?? "
"There's no electricity in the house..." said the lady.
Moral of the story:
Gather all requirements and resources before working on any project and committing to the client...!!!
