Four old  retired guys are walking down a street in Cooktown. They turned a  corner and see a sign that says, 
Old Timer's Bar -  all drinks 10  cents! 

They look at  each other, and then go in, thinking this is too good to be  true.

The old  bartender says in a voice that carries across the room, 'Come on in and  let me pour one for you! What'll it be, Gentlemen?'

There seemed to  be a fully-stocked bar, so each of the men ask for a martini.. In short  order, the bartender serves up four iced Martinis... shaken, not stirred,  and says, 'That'll be 10 cents each, please.'

The four men  stare at the bartender for a moment. Then look at each other...they can't  believe their good luck. They pay the 40 cents, finish their Martinis, and  order another round.

Again, fo ur excellent Martinis are produced and the bartender again saying, 'That's 40 cents, please..' They pay the  40 cents, but their curiosity is more than they can stand. They have each had two Martinis and so far they've spent less than a  dollar.

Finally one  of the men says, 'How can you afford to serve Martinis as good as these  for a 10 cents each?'                               
'I'm a  retired tailor from Sydney,' the bartender said, 'and I always wanted to  own a  bar. Last year I hit the Lottery for $25 million and decided  to open this place. Every drink costs ten cents - wine, liquor, beer, it's  all the same.'

Wow!!!! That's quite a story,' says one of the  men.

The four of them sipped at their Martinis and couldn't help  but notice seven other people at the end of the bar who didn't have drinks  in front of them, and hadn't ordered anything the whole time they were  there. One man gestures at the seven at the end of the bar without drinks  and asks the bartender, 'What's with them?'

The   bartender says, 'Oh, they're all grey nomads from the caravan park, waiting for happy hour when drinks are half  price.'
