The public now have a new product to enjoy, tiny people! And you run a shop that tries to sell them! You can source tiny people from jails, homeless shelters, science labs, and registered breeders. You could also catch some in the wild. Or shrink normal sized people yourself with an expensive shrink ray. The world is a different place thanks to the size reduction law. And you need to turn an abandoned and empty shop into a thriving tiny people store!
