As of a few weeks ago, they have a sign posted at the produce entrance starting that they are required, though no sign at the checkout entrance that I've seen. If someone doesn't have one, they have a small basket with disposable single use masks available by the sign. Most customers I've seen there are smart and wear their masks but management and employees don't enforce it. For those people whose biggest inconvenience in life is a piece of cloth on their face, you'll still be allowed in so don't worry, no "oppression" here.
I think a lot of places are just "recommending" them. If you're worried, as long as you have yours on you should be safe. As for the brands i can't answer that. Sorry!
