Just a a run in with gym worker about mask. He said I have to wear unless I show him a card defining my medical exception. Has anyone had this happen or have know what the card looks like? This is fucking bullshit. Thanks

Edit : so for some more clarification I have been going to the same gym without a mask since they opened and no one has said a word. He also told me there policy changed in the last 2 weeks but I have to received any info or seen anything posted.
