It is not much different for most people. No more risk level for people under 60 that do not have other health issues.
It’s still a big deal as a whole.
My opinion on this issue specifically. Costco can do what they want to virtue signal. We can choose not to go. We can also contact them to let them know. I won’t be going until they remove this ridiculous rule but that’s my choice. It also makes sense to let them know. Their revenue is likely fine as are box stores are in high demand but at some point they need to end this dumb policy and more revenue from customers sitting on the sidelines is a pretty good justification to do it sooner than later.
Can we all agree that it shouldn’t be nationwide policy?
