Two villagers come to the city for an outing and went to a restaurant to have coffee.
They asked the waiter about the price of coffee.
Waiter replied, hot coffee- 3 Rs. and cold coffee 5 Rs.
One of the villager ordered two hot coffees for them.
Waiter brought coffee and served them.
One Villager drinks coffee so fast that his tongue got burnt, then also finished it.
Other Villager drinks it slowly.
The first villager asked the other to drink it fast else coffee will get cold and the waiter will ask for 5 Rs.
