A beer doesn't care if you are late. And you can always have several different beers and not feel guilty. Beer stains wash out. You don't have to wine and dine a beer. Your beer will always wait patiently for you in the car.
Beer is never late.
Hangovers go away . Beer labels come off without a fight. When you go to a bar, you know you can always pick up a beer. After you have a beer, the bottle is still worth a dime. A beer won't get upset if you come home with beer on your breath.
