Hello and Aniomashimika.

Welcome to Business Daily from the BBC World Service.

With me, David Kahn.

Today, it's part three in our three-part series on depopulation.

What do you do when there aren't enough people to work?

But if you make it unmanned, this is all resolved.

The solution is to not use anyone at all.

With fewer young people entering the workforce each year, we head back to South Korea,

where some shops and stores are changing.

And going Muinha, or in English, unmanned. In its simplest form, unmanned stores can be vending machines or roadside honesty stores. You've probably used them. But here in South Korea, they're far more than that.

Study cafe, self-rendery, automatic cafe, ice cream store. So how do they work? And could this be a solution to South Korea's dwindling workforce

caused by more than two decades of declining birth rate? All coming up in today's episode of Business Daily.

It's past midnight in the outskirts of Seoul, South Korea, and I felt like some snacks.

You might ask, where would I go at this time?

That isn't a problem, because just across the road from the apartment, there's not one,

but three snack shops that are open 24 hours a day.

The store I've entered is an ice cream shop.

And as you might expect, there are rows of freezers with variety of ice cream.

But there aren't any security guards or a shop assistant.

Just products in full display and an automated kiosk where you pay for what you want.

All I have to do is grab what I want. I'm going to get this

classic ice cream called a piggy bar and pay before leaving.
