Many years ago, I was quite young, and ignorant. I went to work with perfume on. The cook at the restaurant who was the store manager starts screaming, "What is that stench?" I was uninformed about his allergy, and found out the hard way.
I was very hurt, and embarassed. It has kind or cured me from wearing much of any scent. From that point on, I would just shower with soaps or gels of little scent, and threw out all my perfumes.
It has been a long time, and I have never forgotten this. I am very careful not to offend, but you can't please everyone, so I have learned in my years of experience.
How were you supposed to know he had an allergy. I'll bet money he didn't. You were his scape goat for the day.
There is nothing wrong with perfume as long as you don't bathe in it. It certainly is better than having BO.
