There should be sale dates on EVERYTHING!!

WHY must I struggle with the Emerald peanuts container, breaking a sweat as I search in vain for a clear-cut sale date?!?! EVERY single item you find in a supermarket should have a "sell by" date. PEANUTS. Salt. Pepper. Tea bags. Candy. Gum. Not just the usual suspects like milk. Good God, it's frustrating! It all stems from the "worms in my Rice Krispies Incident" from 1980 or so, which also was the last time I EVER bought anything beyond lunchmeat, a paper, or lottery ticket from a deli or corner store. Though that was dad's fault. And he DID take it back, after I burst into tears upon seeing the scores of white worms...AFTER I'd had most of the cereal. Christ, I wanna vomit NOW, 27 years later, upon thinking of that awful morning. SALE DATES!!!!!
