If drinking beer is considered Presidential business then I had no idea I was so into government work lol. While on a trip to visit the home town of his great- great- great grandfather - Moneygall- Obama decided to do as the locals do. He and Mrs. Obama downed a few pints of Guinness and even made a toast to the whole bar.  According to tmz.com , Obama paid his tab in full ( no word on just how much that was) and told the bartender,

"I just want you to know that the President pays his bar tab ... that's how we do things."

And again ,I had no idea paying for the beer you drink at a bar was a presidential thing to do, I should get into politics :)
