Final answer:
The phrase 'and thus' does not directly imply anything about the typical Japanese KFC store's size without additional context. The idea of threshold population mentioned in the references could suggest that establishments like KFC stores aim to serve a significant number of customers to maintain profitability, but this can vary widely.
Step-by-step explanation:
When discussing the implications of the phrase "and thus" regarding the typical Japanese KFC store's size, it seems somewhat disconnected from the information provided. However, based on the context clues available in the given references, the phrase "and thus" could imply that a typical store is designed in a certain way to accommodate a specific number of customers or a type of service.
Unfortunately, without a direct link to how KFC stores operate or their size, we cannot accurately determine if it means that a typical Japanese KFC store has more customers. Nevertheless, it is worth noting the concept of threshold population as mentioned in relation to different establishments like Wal-Mart and Starbucks.
This could hint at larger establishments typically requiring a higher threshold population, thus implying they serve more customers. On the other hand, smaller businesses, like the "Mom and Pop" inner city grocery stores mentioned, may operate without the need for large customer numbers or economic profits, possibly focusing on community service or having a loyal customer base.
