I think it is an good idea to put some seats in public area. Today, almost all of have cellphones and it is easy to get in touch with others. We can know our friends life without meeting thanks to e-mail and SNS. However, I think it is very important to meet friends and talk on face-to-face. So, if there are more public seats, we can talk more easily. Some people say if we have public seats, teenagers will have them to themselves and people who really want to use them cannot use do. But I think it is not only to be said about teenagers. We can solve the problem by setting priority seats.
