If I smell something, does that mean I'm taking the smell away?

If were to smell a fresh baked loaf of bread, or someone's perfume, would that mean there would be less fragrance for someone else to smell? Would the scent become weaker until there was none left?

To set off your sense of smell only takes a few thousand molecules of an odor or fragrance. A loaf of bread or someone's perfume are giving off literally trillions of individual molecules, and refreshing the output of those molecules every second. Your inhaling a few of those molecules is not going to deplete but a minuscule percentage, in effect, having a meaningless depletion of the total. 

So go ahead, and sniff that baked bread.
