A restaurant always has plenty of seating but customers still wait. Which scheduling strategy is described?

Chase-demand scheduling is a strategy where resources are adjusted to match customer demand in real-time, often used in environments with fluctuating demand, such as manufacturing. It does not apply here, as the restaurant has ample seating available and is not adjusting resources based on immediate demand.

Consumer self-service refers to systems where customers take initiative to serve themselves, such as ordering at kiosks or buffets. While this might reduce wait times, it does not explain the scenario where customers wait despite available seating, making it an unsuitable strategy in this context.

Appointment scheduling involves setting specific times for services, common in medical or personal care settings. While it shares similarities with reservation scheduling, it is not typically associated with dining scenarios where customers arrive at their leisure, making it less relevant in this context.
