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.
They feel weak and powerless and they want to pull a powertrip on people while feeling righteous.
If this guy was really concerned about this he would have stayed far away from me and just reported me to management. If he really cared about masks he'd know the valve ones do even less to protect others, he'd know some people can't wear them and he'd know the bylaw which excludes exemptions. If he really cared he'd have seen the research doesn't show any evidence they work, but I digress.
If he was really scared about the virus he'd have his groceries delivered. In fact, this guy was using one of those little baskets...if he was so concerned about catching it why doesn't he wait to go to the grocery store until he really needs it?
