One day, a duck waddled into a corner store.
He approached the manager and asked:
“Do you sell grapes?”
The manager says:
“No, we don’t sell grapes.”
The disappointed duck goes home. But not to be deterred, he came back the next day and asked the manager:
“Manager, do you sell grapes.”
The manager replies again:
“No, we do not sell grapes.”
The duck goes home, only to come back a third day in a row, to ask the manager:
“Please sir, do you sell grapes?”
This time the manager says”, “
“No, we don’t sell grapes! If you ask one more time, I will nail your beak to the floor!”
The duck goes home, saddened once more.
But not to be denied, the duck comes back the fourth day in a row. This time,, he asks the manager:
“Mr Manager, do you sell nails?”
The manager says:
“No, I don’t have any nails.”
The duck says:
“Okay, good. Do you sell grapes?”
