A bit of uniform camouflage

Paramedic's uniform shirt, Lions Gate Hospital, North Vancouver, BC

Last week I ran into a Paramedic at the Lions Gate Hospital in North Vancouver. The top button of his shirt was undone and I noticed that the placket and buttons were just there for appearance., The actual garment closure was a zipper hidden behind the placket.

This zipper is designed to make getting dressed faster and easier, while still maintaining the dressier appearance of the button closure.

I wonder if patients would really notice if the shirts did up with a zipper? And more to the point would they care?
