Such a minor dilemma! But I know Mumsnet generally recommends unscrupulous honesty - so I thought I'd ask what you think of this:
I'm at work and really hungry. I have no change for the vending machine - I have no cash at all. I have to stay until 5pm.
In the kitchen there is a box of flapjacks and cakes for sale. They are in a box with a little honesty box for people to buy them.
Would it be acceptable to take a flapjack now, and put the money in for it on Monday?
Or would this be a terrible crime, and I should stay hungry instead?
