I finally found the dimmer switch !!! Headed to the self check out, 2 of the 4 self-check was opened, both customers occupying were stuck, waiting for an attendance to clear whatever was stuck in the system. I looked for full service cashier, surprise, NONE. The pre-order desk cashier was opened with 3 customers ahead, thinking he might not take me since mine is a store bought. I headed back to the self check, more people lined up there, the 2 customers waiting earlier by the self check were still waiting for someone to clear the system. I put the product on a near by shelf. never to return there again.
