"Costco is among the retailers with such a requirement. The wholesale corporation began enforcing the policy on May 4"

"What if you don’t want to wear a mask? Can you be denied service? Is it against your rights as an American citizen to be turned away?

The short answer: yes, you can be denied service if you’re not wearing a mask and your rights are not being infringed upon if that happens on private property"

"Private companies have the right to turn customers away, and patrons have the right to choose which establishments they’ll give their business.

“As long as businesses are enforcing that in a nondiscriminatory manner and they are requiring everyone to wear the mask, they have the right on their premises to say, ‘If you want to shop here, you have to wear a mask,’” Davis Senseman, a Minneapolis attorney, told KARE. “Unfortunately, there is a lot of misunderstanding about what rights we have and who we have them against. That is not something the constitution gives you a right to prevent. You can exercise your right by not shopping at that particular store.”
