I've been out in the streets & shopping in NYC the past several days. The majority of the people I've seen are still wearing masks. Even in Whole Foods, which I think, is one of the chain stores that have allowed the removal of masks, people pretty much all wore masks. A lot of the 30 and under still have only received one shot so far, or are in the 14 day post vaccination wait, (according to the date they became eligible to be vaccinated.)
Comedian Trevor Noah noted
it's actually quite EASY to figure out which people are vaccinated and which aren't.
(This should be cued up to the 5:28 mark. Fast forward to it if it isn't. And you only need to watch to the 6:35 mark.
