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 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.
