A man walks into a bar and orders a beer. After having the beer, he asks the bartender for the bill. “$3”, says the bartender.
The man just for fun goes on and places $1 coin on the three ends of the table. The bartender gives him a bad look but has no other option but to pick them up.
This happened for 3-4 days and everyday the bartender felt humiliated.
Next time, he orders a beer but couldn’t find three $1 coins to pay the bill. So, he hands the bartender a $5 note.
Now, the bartender gets all excited and thinks that it is his day to avenge the hard time he had because of this man. He then places the two $1 coins at the opposite ends of the table.
Now, with a shrewd smile and with all the excitement he goes to the man and says, “Go on, collect your change”.
The man then takes out a $1 coin from his pocket and puts it in front of the bartender and says, “One more beer please.”
