Really? I was in immersion and we had to suffer through this in Gr 1 and 2. I think it's responsible for my childhood fear of skeletons.

If they're injection molded, and there's a problem with the flow or the pressure, it could produce several runs that have the same void in one pan before someone notices and fixes it.

It looks like a manufacturer's defect to me. Looks like injection molding gone slightly wrong - maybe a bubble or a mold not quite filled up. I worked in a place that made plant pots and sometimes they came out of the machine with gaps in the rims, and I had to stack the good ones and toss the bad ones into a bin for the grinder. Looks like they skipped that bit.

Uh, no, many of us prefer to be called by the nation we belong to. Some of the younger ones would be really offended at being called Indian, especially by white people. Indigenous, First Nations, and native are fine - better than Indian at least.

And every drugstore, grocery store, Starbucks, Walmart, etc...

I think they're also being selective about what time of day they're reporting. Their source claims that my local hospital has an average wait of 3 hours, and it does, briefly, at 8 am just after the shift change. The rest of the day is anywhere between 5-12 hours (or more), but I guess we don't talk about that.
