Work at a pet store and today we had a sale “buy 24 cans of cat food get 4 free” and had so many people buy in huge bulks, seclude some cans and tell me “these are the free ones” and then they tried to argue with me when those specific cans dont ring up free- the computer automatically selects which cans are free. Had a guy ask me why I even scanned the “free ones”. We need to know what’s in our inventory, it has to be scanned, I’m not trying to rip you off. You’ll get your free cans, chill.
