What they do is swap bar codes, or they code organic fruit as regular, or they "forget" to scan in the self checkout, but yes.

So it's just stealing with extra steps.

Amusingly enough the extra steps likely make it worse once caught as it shows intent to defraud and planning.

In some places walking out with a MacBook Neo is a misdemeanor-but putting a barcode for bananas on it and checking out would be one or two felonies.

This is a big reason why retail product barcode stickers (not barcodes printed directly on a package as it comes from the manufacturer) are now commonly printed on frangible stock with built in slices in it which breaks apart in 3, 4 or more pieces if you try to peel it off.

Hardly matters when one may print their own barcode on labels and cover the frangible one.

printing your own sticker requires way more prep than ripping one off a pack of ground beef and sticking it on a pack ribeye steak.
