I had a brief conversation with a Kroger manager regarding theft at the self-checkout register.
She told me of the various ways folks figure out how to beat the system, and the easiest one is by entering the product's code number, instead of scanning it.
"Pero, ¿cómo así, Joseito?"
Así: Organic bananas cost more, so the shopper would enter 4011... for the regular ones.
More daring shoppers would enter a code for a cheaper product and walk away with a ribeye pack of 3...
Enter the code for cheaper avocados, but prepare that tasty guacamole with the real deal.
Si, así de fácil.
