Problem
Manu Narayan owns several first-class hotels worldwide, including properties in Manhattan, Mumbai, and even some in suburbia. He wants to make sure that the human-computer interface is appropriate to each culture but also wants to be able to share the software among all of his hotel reservation departments. Design a nested menus interface for a check-in and checkout hotel reservation system that can be used internationally. Use numbers to select a menu item. Show how each menu would look on a standard PC display.
