All too often in the course of my job, I have people come in that clearly have on too much perfume or aftershave. I try to conduct business with these individuals as quickly as possible and get them out of my office. The scent alone will trigger a major headache, after that I usually get a sore throat, begin coughing, and the symptoms last for days, even weeks sometimes.
Last week I had a gentleman come in who smelled as though he had bathed in aftershave. While helping him, I kept at a distance and did everything I could to speed him along. By the time I had finished helping him, I was already coughing, bright red in the face, and ready to drop. I keep a fan in the office which I point outwards from myself to try and deflect the smell, but it didn't help much in his case. Then he wanted to linger and talk. I went back to working on other tasks, coughing all the while, at one point, I was almost bent double in a coughing fit because I quite literally could not breathe.
He just kept on talking as though nothing was going on. I told him several times "I have to get back to work now, please excuse me." but could not get him to leave the office.
Is there a polite way to tell someone, "I'm sorry, but you're going to have to leave. Your perfume is making me ill."?
