Ladder and clock tower

Sardarji is in Delhi. He is walking on a street which has a Clock Tower when someone asks him if he wants to buy the clock on the Tower. Sardarji says "Yes".

"Give me a thousand rupees and I'll go get a ladder."

The man took the thousand and disappeared. Having waited for several hours the Sardarji figured he was taken for a ride.

On the next day the Sardarji is again walking along the same street and the same man asks him to buy the clock.

"Give me a thousand rupees and I'll go get a ladder."

The Sardarji gives him the thousand and says "I am not a fool.This time, you wait and I'll go get a ladder."
