The new Supermarket near our house has an automatic water spray 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 enjoy the scent of fresh butter . 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.
