I work part-time at a grocery store, which is an affiliate branch of one of the largest chains in the U.S.
At this time, there haven't been any shortages that I have seen. But it may be coming soon. We have received a lot more masks for sale this week, because of the stupid "Delta Variant" propaganda.
I was so happy, however, when leaving work yesterday, to see a group of anti-vax and anti-mask protestors near the store on a street corner holding anti-vax and anti-mask signs, and many cars were honking and yelling out of their car windows in support of them. I recently moved from the uber-liberal Seattle area to Central Washington, where there are far more conservatives.
I can post on this thread again, if I see shortages occur in my store.
