Should they add to the CDC warning if you are sick and work in a supermarket stay home?

I was just at the supermarket and this girl who is putting together my pork chops touches her nose, sniffs, and then roles up the package. I ask if she is sick, and she does have a cold. I am germaphobic enough that I don’t want those pork chops anymore. I don’t want to get sick, not even with a head cold. I realize she has probably touched other items in the meat department, but knowing she just touched that package I did not want it. I think not only should “they” ask children to stay home if sick; but also, people who work in supermarkets. Seems like you could spread a lot of illness to a lot of people.
