Heads up, Costco fans! Next time you’re cruising for free samples, know that you’ll need to be 18 or have an adult with you. Costco’s new rule is all about keeping kids safe from food allergies—no more solo snacking for the under-18 crowd. On the bright side, you can still go back for seconds (or thirds), and the best time to score samples is weekend afternoons. Pro tip: sample-hopping can basically be lunch if you do it right! #Business #LocalBusiness #CostcoHacks
