What Would You Do?

Scenario...

You are in a store. It's a larger store lets call it "All-Mart". You are only there to grab a few things and then head on out. The things that you need are close by the power tool isle. You grab your few items and as you are walking back you take that power tool isle. Let's say you have a mouse sander and want to see if they have any sanding papers that would fit it. As you are standing there perusing the sandpaper and sanders a lady driving one of those automated carts comes by you, goes a few feet away and stops. You stand there still entranced by the many different little gadgets that there are associated with power tools, but alas there are no papers that will fit your mouse sander. The lady in the cart, in the mean time has started doing something somewhat strange. You hear this rattling noise, like plastic packaging being ripped open so you glance down the isle towards her and see her put a pair of little wire cutters down. You hear more ripping and notice that she is totally taking something out of it's packaging. Being dumbfounded that this person is doing this all you can do is stand there and watch in amazement at the brazenness of it all. After all you are standing only 6 maybe 10 feet away. The lady takes what ever it is that she has removed from the packaging and puts it into something else but you can't tell what. You are thinking "Well maybe she needs whatever it is right then and she will pick up the packaging and take it with her to the check out." Then she puts on the power and scoots on out of there, leaving the packaging behind. Being curious you walk over to see what it is. It's a mister that mists water out to keep a person cool so there really is no way she could use it in the store and she left the packaging there.

So if this were to happen to you what would you do? Would you say something to the lady as she is in the middle of opening the packaging? Would you go and find someone after the fact and let them know what you had observed? Would you have had more presence of mind and realized what she was truly doing and gone to find someone before she drove off in her little cart? Does her being in the little cart make it o.k. for her to do something like this?

What would you do? I wanna know. Spill.
