Refactoring TripService By Sandro Mancuso in Meetup Software Craftsmanship Madrid

Some days ago I was in meetup software craftmansip madrid
This is the kata : Trip Service Kata
This is my solution: Solution of TripService Kata
I've learned that it is very important the name of the methods, due to the semantic of them and the meaning of the code.

Also I've watched this video. Sandro Mancuso solves this exercise. I recomend it.
