For my first job I worked at Kmart for a year and a half serving as a cashier and Hardlines Merchandiser. I was very friendly, enthusiastic and good at what I did.
One day they found that I was overriding prices without getting price checks. If a customer said the tag said it was 5.99 but it was ringing up as 6.99 and it seemed believable then I would just give it to them and override it myself without getting a price check because those often took five mins or longer and would hold up the lines. It was incredibly dumb of me looking back now.
I was terminated. I want to put this job on my application because I think it was a great experience and I benefited a lot from it, but I don't know if it'll set me back more then it would help since me overriding like that is considered theft. Also don't know how to phrase that during an interview.
