So, at the doctor's visit yesterday, a woman was there with her daughter (3 or 4 years old). They were loitering at the check-out area and generally getting in the way. Finally, they talked to the check-out lady and were redirected to the check-in area, which is at the other end of the counter.
After this woman and her kid had been standing and brushing all around Annika, the baby and me, I stood at the check-out counter while paying and listened to her tell the check-in nurse all about her daughter's vomiting and fever which kept them up all night.
Did the woman bother to use the sick child waiting room or even attempt to keep the child away from anyone else? No - the kid was still standing next to me. Why expose the world? No one wants the throw-up virus.
