Despite the fact that you cover your table with a towel, or conscientiously replace the headpiece tissues, the leather or Naugahyde often retains some memory of a noxious odor. I am reminded of the war that took place on Eastern Airlines between smoking and nonsmoking passengers. Both wanted their rights to the air. Nonsmoking patients are quick to detect doctors that smoke. Despite not smoking in their office, their clothing betrays them.
Smoke permeates everything with which a smoker comes into contact.
What we need to remember is that patients do not prefer the same scents. Surely you have encountered pipe smokers who cannot understand why everyone doesn't like the smell of tobacco smoke. Cigar smokers are a breed unto themselves. While they insist that not smoking while treating patients gets them off the hook, the cigar odor never leaves them. Think of the patients you are currently treating.
