Wouldn't it be easier to just look at SN registered against inventory to see if something is registered but a sale hasn't been recorded yet?
Then you know the store and could have their retail loss prevention look into it. Seems more systematic than a "bag check". They don't check customer bags right? For example in a mall location.

The only ambition you should have in retail is to get out of it as soon as you're able.
