A couple wanted a bag of Lays chips that were buy one get one for 50% off.
They tried to say there wasn't any more plain one in the front of the store. From my register I could clearly see another display of them.
My store, the majority of the time, doesn't charge people for 50% off if they are only getting one.
So of course they made me void off the chips and this big size thing of dip which made the total void over $5. This meant I needed an override key, which took a few more minutes to get because we were busy.
