It's Now Okay to Steal

Oklahoma is a state that prides itself as being the "Buckle of the Bible Belt" based on the number of huge churches which are filled every Wednesday night and most Sundays. The high moral ground occupied by all these Bible-thumpers has been a protection to the people of this state against all forces of nature and acts of God (except tornadoes, wild fires, ice storms, drought, and more tornadoes). This is a state that has constitutionally defined marriage and still allows the display of the 10 commandments in government buildings. That some of the commandments are scratched and faded should not imply that the rule of law is not held in the highest esteem and absolute honesty expected of all the ladies and gentlemen calling themselves residents of this great state. Unless it was someone else's mistake, and you're really just taking advantage... not stealing really, because you didn't actually take anything... and not lying, if nobody asks you any direct questions. After all, they have insurance to cover these sorts of things, and I've been ripped off a time or two, so it's just karma paying me back. I feel completely justified in my ability to rationalize.
The point of these ramblings can best be illustrated by a story I'd like to share:
We recently purchased new cell phones, the kind with a slot for a memory card so you can save songs and pictures on the phone. We ordered the memory cards online through Best Buy because that was cheaper than ordering the card through the phone company, or buying them in the store. We opted for free shipping rather than in-store pickup because it was free and we weren't planning on heading into that part of town anytime soon. Several days later (4 days longer than the "expected" ship date and at least 3 trips into that part of town) a large box arrived at our doorstep. Much larger than would be needed to ship two small memory cards. Opening the box revealed two Sony Cybershot digital cameras. Being the savvy consumers that we are we immediately kept the cameras and called to complain that we didn't get the memory cards. No, wait, that's what people thought we should have done. We took the cameras to the Best Buy (4th trip to that part of town) and exchanged them for the memory cards. The exchange went something like this:
Me: We ordered memory cards but got these cameras. Can I exchange them for the memory cards?
Customer service rep: (incredulously) You want to exchange them? I'd just keep the cameras.
Me: I didn't pay for cameras, and I don't really need another digital camera.
Customer service rep: Okay. (On radio to electrics manager) I need two micro memory cards for a customer who received two cameras by mistake.
Electronics manager: Why doesn't he keep the cameras?
Customer service rep: He says he doesn't need them and didn't pay for them.
Electronics manager: Okay, but I'd just keep them.
Customer service manager: What's going on here?
Customer service rep: This guy ordered two memory cards for like 40 bucks but got these two cameras which sell for like 300 bucks, and he wants to exchange them.
Customer service manger: Wow, I'd just keep them and buy new memory cards.
Customer service rep: Me too, but he wants to return them.
Customer service manger: Hmm, must believe in karma or something. (To me) Well, it pays to be honest, I guess, so we'll give you one of the memory cards free.
Me: (Somewhat happy and somewhat disgusted) Thanks.

Is it so rare for a person to be honest and not try to take advantage of someone's mistake that everyone at the store was shocked that I would bring in 300 dollars worth of merchandise to get my 40 dollar memory cards? I guess retail is a lot like politics, if you expect people to be dishonest, self-serving, and cheats, you'll get what you expected.
