I think they get desensitized to their own smell so they feel that no one else can smell them either, thus they reapply. I work in a hospital where sensitive people come in and out all the time so it is in the employee handbook that no heavy perfumes are to be worn nor ANY scented lotions. The lotions also come into play with the fact that the chemicals that create the scents breakdown the material in the gloves so it is really a safety issue there. Still, loads of people wear them to the point of gagging those around them. I consider that a management thing since it should be enforced; not only for the health of the workers but for the patients too.
