Note: I'm an old fart pede, so what I tried may not work for younger pedes.
Had to take my tax documentation to H&R Block. Walked in without a mask and was greeted by a big fat black gal (you know the type, 10" fake nails, those big caterpillar fake eyelashes, and a ghastly hair weave) wearing two masks and sitting behind 1" thick plexiglass.
Her first words were "please put a mask on."
I played dumb and pretended I didn't hear. She says even louder "put your mask on."
I reply "I'm sorry I can't hear you with the masks on. I have a hearing deficit. Please speak louder."
She grunts and shouts so loudly everyone in the office heard her -- "PUT A MASK ON."
I say "I'm so very sorry. I have to read lips in order to fully understand. Please lower your mask."
She shouts even louder "PUT THE MASK ON."
By then she's hyperventilating and can't speak. So she leaves the reception desk and sends up a big tall black dude who's also double masked.
Wash Rinse Repeat
He starts to hyperventilate and lowers his mask enough to tell me "PUT A MASK ON.
I reply -- Medical Exemption.
He freaks and leaves the reception area.
The gal I wanted to see from the git-go comes up front, takes my papers without a peep and I leave -- Mask-Free with a Shit-Eating Grin.
Right, and - with ME/CFS, when you go into PEM (post-exertional malaise) after too much physical or mental exertion - you cross the threshhold into anaerobic metabolism.
So that kind of 'burns smokier' than regular metabolism, and throws off even extra carbon dioxide in your respiration. So when you're walking in a store etc., with CFS you'd be even more compromised/oxygen-starved with a mask on.
To demonstrate this for red-pilling, anyone can get a little 'pulse oximeter' online that clips on your finger, and check your own oxygen levels. See how oxygenation quickly drops toward or into the danger zone under mask conditions.
Better still, wear one on a lanyard around your neck and demonstrate this to anyone you encounter who is interested. Look up the work of Peggy Hall from The Healthy American for more on how masks lower O2 & to what levels, even in healthy people and elite athletes.
I did that when in an ER last year. I had lots of time while waiting for an actual doctor to see me :) I watched the meter readouts, and it would drop about 5-6% oxygen level with the mask on. I did it every few minutes and it was pretty consistent. (so now, in addition to mostly brain-damaged leftists walking around, they are oxygen-deficient brain-damaged leftists :) )
This is my daily existence in korea. Cyclist, joggers, babies, all wearing masks. Frequently see guys on scooters or bikes, not wearing a helmet, but masked up.
