Ok, but that's for me to decide, not the restaurant.
A restaurant with chronically slow service is not a good restaurant because occasionally it coincides with my desire to have a slow experience. It's just a bad restaurant.
A restaurant with chronically fast service is a gold restaurant because I can choose to have a fast experience or a slow experience depending on the context.
Your time preference likes is your call. Some people are short-term others are long-term. You don't have to prove anything to me, I am just some guy on the internet. Enjoy your haMbUrGer 😉
