Well, having a six-year-old helps! We were at the pool supply store yesterday and he loudly asked “Mommy, why isn’t everyone wearing a mask here???” To be fair, we don’t have a mask mandate in our county, though all large retailers and restaurants are requiring them.
At the big box stores, I make a mental note of it, but really, I don’t expect someone making minimum wage to risk physical harm to themself (a real possibility here) to get into it with an ignorant idiot over a mask. As long as the vast majority wear masks, which they do in the big stores, I’m mostly okay with it.
