Here’s a neat trick.

Get a dollar bill. The crisper the better.

Look at it face up, where you can see George.

Look at the upper left hand corner. Bend back a little triangle, just inside the green part, no more than a quarter of an inch.

Okay? What do you have. A dollar, right?

Go to the vending machine down the hall, insert it in the slot, and watch as it is rejected. Repeatedly.

Now, unfold the little triangle, and it’ll take it on the first try, and you can have your crackers.
