The Manager of Toyosu Express is facing the following problems: - The average dining time is more than 100 minutes during lunch hours, leading to a low turnover of tables. It is observed that a high proportion of guests spent a long time chit- chatting with friends after their meals. Guests complained that the reservation hotline is always busy. It's almost impossible for them to make a reservation in advance. During lunch hours, they need to queue up for a long period of time before they are seated.

Based on these problems and the information of Toyosu Express provided on page 9, propose and explain any four (4) areas on maximizing revenues for Toyosu Express with examples. Answer the question in paragraphs.
