"Australian Tourist" joke

Bruce, a middle-aged Australian tourist, visits the red light district of Amsterdam and enters a large brothel. It's his first time in Europe.

The Madam asks him to be seated and sends over a young lady to entertain the prospective client. They sit and talk, frolic a little, giggle a bit, drink a bit and she sits on his lap. He whispers in her ear and she screams and runs away!

Seeing this, the Madam sends a more experienced lady over to entertain the gentleman.

They sit and talk, frolic a little, giggle a bit, drink a bit and she sits on his lap. He again whispers in her ear and she screams and runs away!

The Madam decides that only the most experienced lady, Lola, would do!

Lola looks a bit tired, but there is nothing she hasn't done already and absolutely nothing would surprise her. They sit and talk, frolic a little, giggle a bit, drink a bit and she sits on his lap. He whispers in her ear and she screams louder than the previous two and runs away! Madam is by now, absolutely intrigued, having seen nothing like this in all her years of operating a brothel.

She asks, "What did you want to do, to make them run away like that?"

Bruce said: "I just asked if I can pay in Australian Dollars".
