At the homebrew store, Paul checks out the shelves.
Paul: So many flavors, spices, stuff...
Homebrew store employee: Stay away from that. Nothing on that shelf is for beginners like you.
Paul: Is the red or the blue thermometer better?
Homebrew store employee: Forget both. Just get a can of malt extract, that is idiot-proof.
Paul: What is this stuff?
Homebrew store employee: Just put it back. You cannot handle that anyway.
Paul: Maybe in a few years, if you practice and do your homework and listen to your local homebrew store clerk.
Paul: Screw that! You can't tell me anything! I'll just buy and brew whatever I want and there's nothing you can do!
Homebrew store employee: What...?
Paul: Take that!
Homebrew store employee: Works every single time.
Till he actually has a clue.
