Why do people look down on a receptionist in a hotel?

Some people treat us very poorly in the society just because we work in the reception business in the hotels. And I still don't know why.

I know 3 languages, I have 2 college degrees, I also got computer and coding skills. But I work in this field because I live in a terrible city with poor opportunities, and economically my country is so weak.
