Some H-E-B employees are urging the company require masks for shoppers in its stores. The state's largest grocery chain, San Antonio-based H-E-B is adopting a policy of only "expecting" its customers to wear masks. On Tuesday, some H-E-B workers asked the community to support them in "calling on H-E-B corporate management to ensure that the customer mask policy is enforced in a way that does not endanger a worker's physical safety."
