Four out of town retired policemen are walking down the street when they turn a corner and see a sign that says "Policeman's Bar" over the doorway of an establishment that doesn't look all that well kept up.

They look at each other then go in.
On the inside, they realize, in this case, they could judge the 'book by its cover' a real dump with sawdust on the floor & a bunch of mis-matched tables & chairs.

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

There seems to be a fully stocked bar with lots of high end booze.
The men all ask for a martini.
In a short time the bartender serves up 4 iced martinis and says, "That'll be 40 cents for the round, please."

The four retired policemen 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, four excellent martinis are produced with the bartender again saying, "That's 40 more cents, please."

They pay the 40 cents but their curiosity is more than they can stand.
They've 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 dime a piece?"

The bartender replies, "No doubt you've noticed the decor in here and the outside of the place ain't nothin' to write home about.
I don't waste money on that stuff.
But, here's my story. I'm a retired sheriff's deputy and I always wanted to own a bar.
Last year I hit the lottery for $45 million and decided to open this place for the real police.
Every drink costs a dime, wine, liquor, beer, all the same."

"Wow. That's quite a story." says one of the men.
As the four of them sipped at their martinis they couldn't help but notice three other guys at the end of the bar who didn't have a drink in front of them and hadn't ordered anything the whole time they were there.

One man finished his martini and, gestured at the three at the end of the bar without drinks and asks the bartender, "What's with them?"

The bartender says, "Oh, those are retired Chicago Cops; they're waiting for happy hour.
Drink's are half price then."
