What are the examples of most common services we tend to make use of very systematically?

Services is a term that has different meanings. For example people who have greater experience in the area of economics are rather likely to correlate it with one of the most crucial areas that contribute the most to the development of each economy. On the other hand, a lot of people, who are not interested in the above mentioned sphere, tend to think about the previously presented term rather like something that we benefit from regularly, like going to a hairdresser, having our automobile repaired by a mechanic etc.
