Should a five-star hotel have a fair-price supermarket?

I don't think there should be. I am a hotel myself. Five-star hotels provide customers with high-level services, and the target customers are also high-spending customers. If it is not cost-effective to set up a fair-price supermarket only for a small number of customers, the profit is not much, and it will lower the grade of customers to a certain extent, which is not worth the candle, so I don't think there should be a fair-price supermarket.
