Unfortunately, Step #4 is: "The previous steps don't actually work, so you'll have to find some other means of stealing money."

Everyone knows that the code to get free coins from a vending machine is up, up, down, down, left, right, left, right, B, A.

Indeed. The real challenge is finding the secret Nintendo controller in the machine, and accessing it before security tracks you down.

I'm not sure if it's intentional or not, but the OP graphic reminds me of the Underpants Gnomes' business plan from South Park:

It is. It's also a long-used meme on 4Chan.

And speaking of 4Chan, I've seen quite a few similar info posts like these on the site, which makes me think that they're more along the lines of troll-calls rather than actual maintenance modes.

But I'll head down to the bus station tomorrow and try it out.

Step 4 reminds me of that old Sydney Harris cartoon with the one fellow reading the other fellow's formula on the chalkboard and the first fellow says "I think you might want to be more explicit in Step 2". Step two says "And then a miracle occurs".

I have seen that as a Far Side cartoon.

Obviously fake if you have seen the coin mechanism. Coin mechanisms are pretty standardized (not a formal standard, but they are pretty interchangable). Basically, it's just a device that checks the size and sometimes the weight of the coin, then dumps it into a container. Depending on machine, this container may be built into the construction or just a random container put there. In my pinball machine, I use a plastic cookie box. The point is that once the coin pass the check and drops into the container, it's there and it can't go back out by non-manual means.

There are maintenance modes. Some are accessible from the front (often by pressing several buttons on startup), but these usually just gives status info. For more advanced modes, you need to open them and push buttons on an internal panel.

There are also occasional bugs. On the coffee machine when I went to university, if you pressed the button for ordinary coffee repeatedly fast enough, something went wrong and it went into a selftest and gave you a free cup of coffee. I suspect that it happened if one managed to get a click in before it had finished processing the previous click. It only worked on ordinary coffee, though, not on chocolate, so I seldom used it.

It is a 4chan diagram. Look in the corner- a mention of Anonymous.

There is a similar code, 4231,IIRC that allows access to certain information, such as number of cokes sold in each slot, amount of change, by each coin. ( which is inaccurate, since it is so rarely reset), but that is all it allowed, read only inofrmation

Default Not if the machine was designed competently

(more content, final edit, please post this one instead)

Though I am no expert in vending machines I imagine what happens is:

1) Customer drops coins into slot which goes into a temporary holding bin

2) If the sale was successful/not cancelled, the coins are dropped from the
temporary holding bin into the main bin which is a secure lockbox where all the proceeeds from previous
sales are kept. (Someone must physicaly open the machine
and the lock box to get to it's contents), ELSE

3) If the sale is cancelled, the coins are dropped from the temporary bin to the coin return tray instead of the main bin.

This would be the easiest/most logical/inexpensive way of doing this so I can't imagine anything that would cause a vending machine to pay out like a slot
machine short of tearing the machine apart with an industrial shredder which is used to destroy discarded ATM machines.

Some machines do accept denominations other than quarters, so this could be done with the change bin (the third bin aloing with the main and holding) through software, but I doubt there would be any way to empty this through front panel only "cheat codes"; There would be a button inside the locked machine you have to press to do this.

(this all assumes the machine was designed by competent engineers, so if there is a machine out there with such a serious flaw, I'd like to hear about it.
