Used to work near a tannery - smell that and you don't want to live! Thank goodness they closed down. Also hate the smell which comes from breweries it used to make me feel really sick when George's Brewery were using something - I think it might have been malt or maybe hops, don't know much about brewing beer. They have closed down too. Have you noticed that male cats spray and you can't find where they have sprayed so you have to wash the whole damn place out.
Like the smell of fried onions, toast, fresh washing, cinnamon buns.
