Beer Festival

After the Great Britain Beer Festival, in London, all the brewery presidents decided to go out for a beer.
The guy from Corona sits down and says "Hey Sen~or, I would like the world's best beer, a Corona."
The bartender dusts off a bottle from the shelf and gives it to him. 
The guy from Budweiser says "I'd like the best beer in the world, give me 'The King Of Beers, a Budweiser."
The bartender gives him one. The guy from Coors says "I'd like the only beer made with Rocky Mountain spring water, give me a Coors."
He gets it. The guy from Guinness sits down and says "Give me a Coke."
The bartender is a little taken aback, but gives him what he ordered. 
The other brewery presidents look over at him and ask "Why aren't you drinking a Guinness?"
The Guinness president replies: "Well, if you guys aren't drinking beer, neither will I."
