The new Supermarket near our house has an automatic water mister to keep the produce fresh.
Just before it goes on, you hear the sound of a thunderstorm and the smell of fresh rain.
When you approach the milk cases, you hear cows mooing and witness the scent of fresh butter fat.
When you approach the egg case, you hear hens cackle and the air is filled with the pleasing aroma of eggs frying.
So far I have been too afraid to go down the toilet paper aisle.
