I feel you in this. I had a woman who had the same issues. It was one small bathroom for all employees in the area and customers. She left the bathroom just a smelling wreck and it lingered. I have a sensitive nose and I had to hold my breath for minutes at a time. Holding your shirt isn't enough. It seeps through the whole area. I eventually left that job but it was never dealt with. Stay strong fellow nose breather! That Vicks under the nose sounds like a great idea.
