I Want That Free Coffee

This morning I was getting my coffee card punched at Jazzman's Cafe and I couldn't help thinking of a Seinfeld episode that pointed out the ludicrous nature of this entire exercise:

Episode 166: The Strike

At the coffee shop:

ELAINE: (To waitress) Oh, nothing for me. (Waitress leaves) I'm going to "Atomic Sub" later.
JERRY: "Atomic Sub"? Why are you eating there?
ELAINE: I got a card, and they stamp it every time I buy a sub. Twenty-four stamps, and I become a submarine (makes a gesture) captain.
JERRY: What does that mean?
ELAINE: (Embarrassed) Free sub.

Later:

ELAINE: Oh, I can't believe it! I've lost my "Atomic Sub" card!
JERRY: So?
ELAINE: I've eaten 23 bad subs, I just need 1 more! It's like a long, bad movie, but you want to see the end of it!
JERRY: No, you walk out.
ELAINE: Alright, then, it's like a boring book, but you gotta finish it.
JERRY: No, you wait for the movie!
ELAINE: (Irritated, and through clinched teeth) I want that free sub.
