The physicians and surgeons who treated members of Saudi royalty (yes,they would come to us) were the same physicians and surgeons who treated the people living in the many public housing blocks located nearby.
I've worked in the housekeeping departments of two other hospitals years ago in the ER.
Today I work in a third ER in a hospital in southern NJ supervising a small crew keeping clean and sanitized a very busy, large and at the same time compartmentalized ER that is in a largely middle to lower middle class area.
It's also in an area with a county jail nearby so we get criminals bought in and the area is also on the outskirts of the NJ Pine Barrens with a large homeless population camping out in the woods.
We get those folks in a lot and they're a whole different species.
