How many does it take?

A guy goes and sits at the bar table and asks the bartender for a drink. After the drink the man looks in his pocket and says "not yet" and asks the bartender for another drink.

After that drink he looks in his pockets and says again "damnit not yet".

After another 3 drinks later the bartender finally asks " Why after every drink you look in your pocket and say not yet??"

The man replies "it's a picture of my wife, i'm not going home until she looks good"
