The owners of Carling, Stella Artois and Fosters walk into a bar together. The bartender realize these are the owners but decides to ask what they want to drink anyway.
He asks the Carling owner, "what would you like?" and he responds, "I'll have a Carling! The best beer ever!"
So the bartender gives him one.
He asks the Stella owner, "How about you? What would you like?" He responds, "Fosters of course, why would you choose anything else?"
Finally he asks the Fosters owner, "Let me guess? Fosters?" He says, "Nah mate, I'll have a water. If these fellas aren't drinking, then neither am I."
