This is a very subjective judgement of smells. Take stinky tofu for instance, some take it for a delicacy with wonderful smelling but others treat it as the most nasty food in the world. Take another example for this, we always think baked bread is a kind of fragrant food which is filled with sweet aroma. But there was a news about a bakery was sentenced for NT$100,000 due to the thick baking smell. That was flabbergasting. The fink said the smell was stinking to high heaven and this good whiff of stench caused him to vomit. I think just a few people will take it personally. Smelling good or bad is really a tough call.
