Rightwriter,
Many of these venues, if not all, are private businesses. They have a right to demand that before entering that you either have a recent negative covid test or are vaccinated.
They have a right and responsibility to open safely for all of their customers.
If you don’t want a vaccine or a negative covid test, you have the option of not going into these places.
If you have to work from home and order food from Amazon that is your option.
Nobody needs to risk getting covid because you don’t want a vaccine or a negative test.
