Covid-19, should critical workers be segmented away from the general population instead of at risk people?

The focus during the pandemic was allowing seniors to buy groceries at a special time, since they are an at risk group. The problem with this logic is that some seniors may still work at places with a high probability of virus spread. These seniors may also have a robust immune system. Imagine a person immune to many diseases because they face a  constant exposure to mild diseases. They are grouped by age with people who have compromised immune systems when a deadly disease comers around. 
My idea is that people who are likely to spread disease should get to buy groceries separate from the general population, to create an effective buffer than prevents the spread of deadly disease.

It's an interesting idea, but I don't think it's practical to identify who is likely to spread disease.  The rules got made very quickly, and there wasn't time to develop a perfect system.

And who determines who is suitable to shop when?  I have a friend who has a very weird immune system.  Non responder to all vaccines.  Anything foreign to his body...his body will reject and destroy it.  Does he qualify to shop with old people?  I’m a health care worker, do i qualify?  Should i really be around the general public when i could be covered in deadly diseases every single day?

What "high probability"?  Quit believing the propaganda and fear mongering.

You people think the virus is in every breath and everyone you meet is infected.
