You are on the first floor or upstairs, and the whole building is the writing room of the bank or the bank building. This is different! In the bank building, you have to ask him what he can't and what he can do. This can't be stupid. I'll kick you out later If the office building called Bank Building can be used as a supermarket, Chinese fast food restaurant, gym and clothing store. The main customer base is the people in the building. Just hand out leaflets at the door in the morning, or send them out (fast food, supermarket).
