Final answer:
The correct answer to the student's question about decisions made by large national salon chains is that matters such as hours of operation, services offered, and profit targets are all decided at the corporate headquarters.
Step-by-step explanation:
With large national salon chains, decisions about matters such as hours of operation, services offered, and profit targets are typically centralized and made at the corporate headquarters. This centralized decision-making process ensures that there is consistency across all locations in terms of the experience provided to customers. Such chains aim for standardization, much like the concept of McDonaldization, where efficiency, predictability, calculability, and control are valued. This approach helps the chains to scale quickly and maintain uniform quality and service standards. Therefore, the correct answer to the student's question is d. All of these answers are correct.
