My shop has high windows windows and also a glass ambulance bay which is right in the front corner by the Trauma rooms. It is very nice when the late morning sun peaks through. Really brightens the mood.
ERs are like casinos. Always timeless indoors, the staff and regulars aren't quite right, normal people visit once or twice in their lives, and the house always wins.
The ED I work in now has some windows, by the water. Sometimes I’ll let the patients ramble while I look outside and see what’s going on. Usually big big boats, industrial buildings. Better than a brick wall.
