I liked that the person was serious about the work.
He did even more than he was asked. His suggestions, recommendations, as well as the front of work he has done, are very helpful in our project.
There were situations in which a different freelancer would be angry, something would begin to demand. For instance, I was made a mistake in the task that Plato made his time. Plato, we have to give him the right respect and gratitude, without any of them there... just took and did! For me as a customer, this is also very important.
