There's a big conference of beer producers and at the end of the day, all of the presidents of all beer companies decide to have a drink in a bar.
The president of Anheuser-Busch orders a Budweiser, the head of Miller Brewing Co. orders a Miller Genuine Draft, and the list goes on . . .
Then the waitress the president of Heineken what he wants to drink, and much to everybody's amazement, he orders a Coke!
"Why don't you order a Heineken?" his colleagues ask...
"Naah. If you guys won't drink beer, then neither will I."
