Thankfully I've only had 2 issues, both at the grocery store.
A couple weeks ago one of the employees asked if I had a mask on the way in- this happens fairly often, you just say "I have an exemption" and they say "ok" and you move on. Exempt this time an employee asked if I had an exemption card (which don't exist here) and we argued for a minute before she let me go. I called the store to complain and the manager apologized to me.
Today was my 1st member of the public. Some WuFlu Willy started harassing me as I was going down the aisle (even in compliance with the arrows!) about a mask. Got a pic but sadly the video didn't record. Went on some rant about me getting everyone sick, about his wife being in the cancer hospital, that it was "BULLSHIT" that I had an exemption (wish I'd said the same about his wife), saying that I should send someone else to get my groceries or get curbside/delivery (he didn't have a good answer as to why he wasn't doing it as he was so concerned). He claimed exemptions don't exist in the bylaw (they do, the sign at the front of the store even mentions them lol) and to top it off he was wearing a mask with valves, which they say don't prevent the spread...sadly I didn't think to say that to him at the time.
There was an employee at the end of the aisle so I yelled at her to get security and the guy walked away, stopping only to rant at the employee for allowing people without masks in before leaving.
I'd like to see your sources for the 2% figure. That's just noise, not even a measurable result.
Frankly I don't think there is any good mask efficacy study out there. You can't intuit it from disease spread by state or county, since there are just too many other factors that could contribute. You can't do it ethically in a lab. You can't control for people "wearing them right" or using "the right kind".
And further, I remember when the American medical societies (pre-COVID) told us mask wearing countries like China and Japan actually see zero benefit. The whole thing is a farce.
Thank you! I'll have to go over the study a little more carefully, but first pass they even acknowledge that mask mandates largely went into effect alongside other social distancing procedures, meaning you've already got a high causal density and parsing out single-item effects is impossible. Which doesn't even matter since 2% is abysmal in terms of gains and not statistically significant anyway. Yikes.
