Why does it only cost $10,000 to open a Chick-fil-A?

Could you please elaborate on why the initial investment to open a Chick-fil-A franchise is merely $10,000? Given the popularity and success of the brand, it seems surprising that the entry barrier is relatively low. Does this amount cover all necessary start-up costs, or are there additional expenses franchisees must factor in? Furthermore, how does Chick-fil-A ensure that their brand standards are upheld with such a seemingly minimal upfront cost?
