Services category is stand on main menu. It’s the part of the application that wires all difficult stuff together and gives you easy to understand results. When writing a Service it is a common best-practice to define an Interface first.

On the other hand, we denounce with righteous indignation and dislike men who are so beguiled and demoralized by the charms of pleasure of the moment, so blinded by desire, that they cannot foresee the pain and trouble that are bound to ensue; and equal blame belongs to those who fail in their duty.
