I encountered an issue with employees at this location because my face mask was below my chin during check out. An employee by the name of Kevin loudly demanded that I pull up my mask. I explained to him that I was in my cool down period because of disability breathing but following the guidance of 6 feet away under the CDC's recommendation. He then called me a "fool". Next He summoned the supervisor & I gave same reason. Female supervisor threatened to terminate membership and deny me access to facility. The CDC & ADA state that a person who has trouble breathing should not wear a face mask or cloth face covering. Violating my right under the department of justice ADA violation protocol your employee impeded my exercise of my constitutionally protected rights.
