No one watches to see if you scan every item in your cart.    Most people don't steal, and it's cheaper for Wal*Mart to allow the thieves to ply their trade than it is to put $8.00/hour girls in place to (mostly) stop those who do.

You have more faith in human nature (or perhaps a considerably less
sophisticated understanding of the costs of inventory shrinkage) than 
Walmart does.
