The photo doesn't match. The store is like a diner, very dirty inside. The staff is not permanent, sellers often change. They are not satisfied with their work and salary. But I've never heard of rudeness. They are friendly and communicate with customers.
I very rarely go to this store and every time I want to go in less and less. Of the two cashiers, one works and the cashier is not always in place, even seeing the buyer, the cashier does not hurry to let him go. It feels like I'm not coming to the store, but to their house and asking them to pour tea.
