Work for the public

Nowadays there are a lot of people who don’t wont to work for the public.
There are some reasons:
Most of people doesn’t have a good education and are disagreeable before the public, although you are sad you must seem that it doesn’t happen anything and although you are not very well you can´t express anything.
What is the problem?
The people who work for the public, most of them aren’t pleasant, there have a lot of violent situations, etc. Then, people complaint of bad service. The solution is not easy but it would be possible to have a try. If the workers who work for the public, worked less hours, they wouldn’t be so tired and nervous and possibly they would work better and more relaxed.
I worked for the public last summer and I think that the workers must be in very good humor to support the bad character of people, and before taking a job, I think that they would have to past a test of patience and the good humor.
