Conclusion

It can be concluded that we don't know what the exact future plans are of Jack in the Box, because the manager didn't want to co-operate with us.
But we did have found some information about Jack's way in the future on the official website of Jack in the Box:
"It's Jack in the Box employees who are the driving force behind the brand. At Jack in the Box, we believe that if you take care of your employees, they'll take great care of your customers. It's a philosophy we call “Jack's Way” and it's at the core of everything we do as an organization."

This doen'st tell much about their future plans. But it tells something about the organization.
And we think that Jack in the Box will also use this philosophy in the future.
