He came in with a shotgun demanding the owner to give him all their money.
But the owner said that he couldnt open the register unless he bought something,
so he took some beer, threw a bill on the owner,
took all the money and left.
But unfortunately this happened early in the morning,
so there was'nt that much money in the register.
Money taken: $5
Cost of beer: $10
Well at least he got some discount.
