Not far from me, Vaporesence has a retail brick-n-mortar store. Obviously, people vape there all day, and they have a whole bunch of fluid bottles sitting around.
When I walk in there, I smell a very strong sweet odor, much like walking into an ice cream shop.
That, of course, is an extreme situation. Few places are going to have as many people vaping as that. Plus they have hundreds of juice bottles sitting around and people dripping with them to try flavors.
