Brownie or Fortune Cookie?

"Sir, would you care for the brownie or the fortune cookie?"
- Hmmm they both look rather tasty, which do you recommend?
"I recommend them both. They're both excellent choices. It's up to you, either is included with the price of your entree."
- Oh... I always like getting fortunes. Let's go for the uh fortune cookie there... yea thanks.
"If you don't mind, sir, what does it say? I can wait a sec for you to open and read it"
-Don't you know it's bad luck to read it before you eat the cookie, but I don't believe in luck sure, why not.
"Well.... what does it say?"
- It says "You should have taken the brownie"
"I'm sorry sir, but the cookie is right. You can't also have the brownie it was either or, not both, I'm sorry. Better luck next time"
