So the bar-tender gets him his beer. After 4 minutes the Aussie asks again "Quick get me another beer before the trouble starts."  So the bar tender does his job and gets him another beer.

The Aussie looks at him with a horrified face, and says "now the trouble starts!"  Then he runs out of the bar.
