Some inventory control systems are not well structured for items with expire dates. First-IN, First-out = FIFO, so oldest is sold first - works well as long as expiry is the first date. Some are Last-in, First-out, like dollar bills in the cash where the early ones are busied under newer ones. Foods should be properly hierarched for sale/disposal. Careful financial management that refuses to toss out expired items? Others might amplify this idea.
