Well, I know an ex of mine is allergic to a clove fragrance. Which was the scent of a little satchel I got him, funnily enough. I think it'd be in everyone's interest to ask people if a) they're allergic and b) if they mind. Personally, there are few fragrances I like, and I often beat a hasty retreat from stores that are scented by candles, incense or perfumes. Some of them set me to sneezing and others I feel like I can't breathe around because it just smells horrible to me. On the other hand, I burn a brown sugar scented candle at home that I love. And a buttercream candle. Mmm. Sweet tooth much?

I was miserable often when I danced, because the backstage areas completely stank with perfume and hairspray. I would often feel like I couldn't breathe and ended up putting my foot down about the hairspray (NOT in a small enclosed area, thank you!), which ruffled some feathers.

Anyway, I'm always a little concerned about doing things in an environment that other people are affected by, or can't get away from. Scents and music, or other noise, are on top of the list.
