And I Used to Think I Was Honest

Woman in Line: I was wondering: the soda over there is priced at $9.00 for four boxes. Does this mean that two would cost $4.50?
Cashier at Navy Exchange: I'm not sure. I could ring one up if you like.
WiL: Would you? Thanks. I'd appreciate that. (to daughter) Honey, could you get me one of those boxes?
Girl in Line: You bet.
WiL: You know, I don't mean to be a bother. But yesterday, I'd put two boxes of Coke at the bottom of my cart. And then, I forgot to put them on the counter when I checked out. I got to the car and thought "I didn't pay for these" and - oh, there you are.
GiL: They didn't have Coke, so I got Fanta.
WiL: Here, could you let me know what it costs? If it comes out to more than $4.50, I can just buy the four boxes. (glances at price) That's perfect! Now, if you could ring up two of these, I'll leave them here. That way I will have paid for the ones from yesterday. Does that make sense?
CatNEX: Yes, I got it.
WiL: Oh, thank you! I feel much better now. I was so upset with myself when I realized I had walked off without paying. I would have turned around right then, but I was in a hurry to get somewhere. So, I'm here now.
J: Well, I'm impressed. Not everyone would have come back.
WiL: I just thought to myself "What is the price of your integrity? Five dollars?" I hope it would be worth more than that. Besides, how could I face my children knowing that I had ripped off the NEX?
J: I guess if it was really bothering you...
WiL: Oh, it WAS. I could hardly sleep last night.
Well, thank you, and have a nice day!
CatNEX: So, there are still honest people in the world.
J: Yeah. Kinda restores your faith in mankind, doesn't it?
