WTF Moment - What is that smell?

I was at work at my pizza delivery job the other night and a strange scent hit my nose.  It was slightly sweet and slightly smoky. It put me in the mind of some type of incense being burned.  After a few moments of racking my brain, I figured out what the odor was.  One of my female drivers was wearing some type of light perfume which had a flower-like fragrance.  This same female driver is a smoker and had apparently been puffing while she was out of the store.  Mystery solved.  Perfume plus cigarette smoke equal a hot mess.
