The new supermarket near my house has an automatic water
mister to keep the produce fresh. Just before it goes on, you
hear the sound of distant thunder and the smell of fresh rain.
When you approach the milk cases, you hear cows mooing
and witness the scent of fresh hay.
When you approach the egg case, you hear hens cluck and
cackle and the air is filled with the pleasing aroma of bacon
and eggs frying.
The veggie department features the smell of fresh buttered corn.
I don't buy toilet paper there any more.
