well I never knew that. my wife took my card (I don’t like to shop at big box stores and gave it to our son.) But I have gone to the food court on occasion not knowing the rules and thus without a card. Since the food courts are open, I thought anyone could eat their.
at one Costco we went to forget where the food court was actually outside....maybe it was just open there during the summer months.
they’ve cheeked my picture on the card almost every time. At the food court, the only way to buy the food is with the card.
