I recall the first mega-store that opened locally - it happened to be a Meijer store, though now Super Wal-Marts, Super Targets, and other stores that sell everything are common.
It was interesting to watch what other shoppers had in their carts as they checked out - a gallon of milk, a floor mop, khaki slacks, and a chainsaw… one could start a creative writing contest in which entrants had to write a story based on shopping carts full of disparate items.
