UNITED STATES—Retailer Costco may soon, stop non-members from eating at its food courts, making its establishment a members-only club.

Costco’s popular food court items are known for its low prices. Alongside other items, customers can buy a whole pizza for $9.95 or a quarter pound hot dog for $1.50. People without a Costco membership are currently allowed to purchase items from the food court. Signs have been put up at some Costco locations indicating that the food court will no longer be open to the public.

“Effective March 16, 2020, an active Costco membership card will be required to purchase items from our food court. You can join today. Please see our membership counter for details,” the sign reads. 

While the new rule has not been confirmed, the effective date could vary depending on each location.
