Do you know that you do not have to tell the store what your disability is due to HIPPA laws?
Which provision of HIPPA says "you do not have to tell the store what your disability is", aka, you can simply claim you have a disability therefore you do not have to follow any rule you don't like?
Which provision of HIPPA says that if I don't like a store's "no shoes, no shirt, no pants, no clothes, no service" policy, I can just walk in their with my hairy balls flapping around in the wind?
Now, it's not really my area, but HIPPA generally is about protection against disclosure of medical information. If I need a client's medical records from a prison, I need to submit a HIPPA-compliant authorization signed and dated by that client.
Meanwhile, the ADA is about all sorts of things related to discrimination, but generally about what public accommodations of certain capacities/sizes must do to allow accessibility.
I have not heard of anything that means you can simply claim a disability or medical condition, provide no proof, and you can skirt any rule the business sets such as a mask-wearing requirement. Doubly so if there are mandates in place. I'm guessing there's more to it than that, if it exists.
The other thing to remember, is that someone filing a suit does not prove anything. If the suit survives a motion to dismiss, it means that assuming every factual statement in the complaint is true, there's a non-zero chance of recovery. If it survives summary judgment, it has a better chance. And at trial, you win as plaintiff if you have a >50% chance of being correct. (If you want to get rid of "in an accident? WANT MONEY? Call me today!", then that last thing is what you change).
But all you did was link a video. Can you state it in your own words? Give me a statutory cite. Even better, give me a case interpreting that provision that says exactly what you claim.
Until then it's just Show and Tell with Robert.
