In some nice countryclub,a stranger walks in one day and orders a beer.
The bartender gives him the beer and the stranger goes into his pocket,picks a few coins and throw them over the counter on the floor.
The bartender is asthonished but says nothing,picks up the money and put it in the cashregister.
Next day,the same happens again-ordering a beer-tossing the coins over the counter on the floor.
Again the bartender says nothing,picks up the money and put it in the cashregister.
The next day the stranger walks in, orders a beer and pays with a 1£ note.
The bartender with a great grin on his face,takes the money,put it in the cashregister and he on his turn tosses the money in front of the stranger on the floor and says:your change sir.
The stranger stares at the money for a moment,goes into his pocket and throws a few coins next to the change on the floor and says:i think i'm gonna drink two beers today.
