This no-staff sales model was quite popular for a while in his past life.
There were even those small supermarkets without vending machines, arranged just like normal supermarkets but without cashiers, relying solely on the honor system for payments.
Stores like these often became hot topics, and Cheng Zhu had noticed them several times.
And the staffless QQ stores also had their period of popularity in the country.
They generally weren't located in places with high rent or heavy traffic because they weren't the kind of sophisticated QQ merchandise stores.
Such stores were usually found in residential areas.

Many people might have seen such stores in their neighborhood.
The cost to operate them was actually quite low.
In the process of operation, they didn't involve any labor costs.
