This is what the order says in my county:

I have a breathing condition that makes me unable to wear a mask or face covering. Do I still have to?
No. Persons for whom a face covering would cause impairment due to an existing health condition are exempt from the Board's order.

Does the Board's order require me to disclose my specific condition?
The order prohibits business operators and their employees from asking for specifics or docuмentation if a customer claims an exception for health reasons, or denying admittance or service to that person for not wearing a face covering.

So according to that, you can just claim you have a breathing condition and they can't even demand docuмentation.

Has anyone tried this?

According to what  you quoted, everyone has a breathing condition.
Anything that restricts your full oxygen intake (a mask) causes a breathing condition.

I can't upvote this enough!!!
I'm homebound so I don't go out but I can say that
Father Relyea says he always just puts up his hand and says with confidence, in his New York voice of course,
"Medical Condition"
and they leave him alone.
If a waitress gives him a hard time he asks if they have ever heard of HIPPA laws.  (You aren't allowed to ask what medical conditon.)

Disputaciones:

Yes!  Do both.

We all should simply put our hand up and say, "Medical condition."

If they pursue it further, which according to the Americans With Disabilities Act they should not do in any way----Harassing people with disabilities or refusing them service--then we should be prepared to show them evidence and make our stand.

Peggy Hall at thehealthyamerican.org has lots of info on how to fight the mask "mandates" which are in no way law!

She successfully fought back in Orange County and give lots of good advice on how to fight this whole thing.

I just lie and say I have asthma.

I won't be told what to do.

I am rarely asked.  I look pretty rough, like I might assault a person.

I'm upset with myself that I didn't plan it better and told them about the exception right from the start, that would have been better because they can't do anything about it.

I read about the mandate after I got home but I already knew about it from before.

Now if I go back and use the medical exception, there will be that bad feeling because I didn't do it from the start.

I rather just never go there again and make them pay because I've been a regular customer there for over a year now.

Why? You aren't beholding to that store and people develop illnesses and issues all the time. Not being able to breathe properly is a medical exemption.

Have courage! The most they can do is ask you to leave and you do just that. You can choose to pursue legal action or not but don't let people control you-that's God's job.

If they ask you to leave, ask them in a louder voice "SOOooooo you don't want disabled people in your store?  Are you now discriminating against disabled people?"

Don't lie.  By lying you are not only committing a sin, you are strengthening the fraud which you are trying to extract yourself from.  The people wearing masks are perpetuating the lie that masks prevent the spread of airborn virus.  The people who lied to get out of wearing a mask are also tacitly supporting the same lie with the addition of another lie (that they have a condition which would prevent them from wearing a mask).  If you can wear a mask/ventilator to avoid toxic fumes, you can wear a surgical mask too.  There certainly are medical reasons for not wearing a mask all the time but that's not the reason you are giving for not wearing a mask.  You are specifically saying that you have a medical condition which prevents you from wearing a mask altogether.  That actually is the case for some people.  They simply cannot wear a mask without severe and immediate consequences to their health and maybe risk death.  But I know people who have been medically diagnosed with asthma who regularly wear masks without any apparent problem.  So you can see why the medical exemption is barely believable.  Don't lie.  Just tell them flat out that you refuse to wear a mask.  Let the chips fall where they may.  Why do you want to give business to these tyrants anyway?  There are plenty of people who would love to have your business, mask or no mask.
