I was at a Whole Foods last year and was tired from driving for about 6hrs straight. I scanned one item, set up a paper bag on the right, and then mindlessly bagged every other item in my cart without scanning. I paid probably $3-4 on a $60 purchase.
As soon as I got to the hotel and figured it out, I went back to correct the mistake--but imagine getting harassed or taken to the back for a careless error? I'm sure that happens more often than I hear about.
(PS I am genuinely surprised their weight sensor, that flags an attendant, didn't go off. That thing usually trips if you breathe on it funny.)
The last time I forgot to scan something hiding the back of my cart I caught the mistake as I was leaving and ran to another self-checkout to scan the item. The one employee they had watching over at least 7 self checkout stations thanked me personally because apparently if the cameras caught the error the overworked employee would have been responsible and might have lost her job.
