A guy walks into a bar, sits down, and orders a drink. He starts eating the beer nuts at the bar and he hears a voice say,

Wow! You look GREAT tonight!

The man looks over at the bartender who didnt say anything and just keeps drinking and eating beer nuts and he hears something again!

Thats an awesome shirt! You are amazing!

He looks around and hes the only guy in the place so asks the bartender if he had heard anything and the bartender says, Was the voice saying bad things or good things?

And the man replies, Good things, why?

And the bartender says, It must have been the complimentary nuts.
