All I can say is, if I ever get a HoloLens, walk into my living room with it on and some chick is standing there wanting me to try a new perfume fragrance and is attempting to spray it on me, I'll trash it. I always hated that when entering a department store in a big mall.
Yes, I know it doesn't transmit smell (yet, you never know). It's a joke.
However, if they have a taste testing counter for frozen yogurt or chocolate covered strawberries and want me to sample their product, I might cry because I won't actually get to try it.
