both are important. Of course, it depends on what type you drive. For example, if you run a snack bar, personally, products are more important than services. After all, small shops rely on the taste of products to attract consumers. They pay more attention to taste and affordable prices, and service is not very important. But good service is certainly more attractive to consumers.

if you run a star-rated hotel, the two are equally important. Think about it, high-end restaurants, people who come here to eat, in addition to eating delicious food, are here to enjoy the service. So actually these two points are indispensable.
