It might let you see through it. Which is what they DON'T want.
They want the customer to open the fridge because the act of opening the fridge is a commitment to a purchase. If the product you want isn't there you are much more likely to purchase something else that is there because you've already made the mental decision to commit to a purchase in your head for the other product that you did want.
This is all "how can we optimise this interaction even more, and even more, and even more?" over time. There is always one more thing you can do to further manipulate sales out of people that otherwise would not occur. The simplest interactions will continue to be optimised further and further, in excruciating detail and thought about how the psychology plays out.

Can't buy anything in the fridge if there's nothing in it. :think-about-it:
