You don't have to wear it. You have a choice, wear it or do your business elsewhere. This isn't public property, it's a private business. They can ask you to leave, and if you don't you're trespassing. That is the law.
>The business is infringing on her liberty
Absolutely false. She's free not to use that business. Do you think "No Shoes, No Shirt, No Service" infringes on liberty?
No it's not. Trespassing from the property is not conversion, all they have to do is mail her a check and close her account. A bank can absolutely trespass someone. Do you think if a customer goes in the bank and starts causing a disturbance they can't make them leave? Nonsense.
You're the idiot that said "sue me for trespass". I wouldn't talk about others getting a brian.
