I start working at KFC

In a few days I start working at a KFC and I feel a little anxiety and pressure because I have never worked in any fast food restaurant. Furthermore, I don't like being in front of the public, I am a fairly introverted person and sometimes I think I am also clumsy and that makes me afraid of not being able to do it well. I know that I am capable of a lot and a large part of the experience will have to do with how my colleagues receive me, but even so I feel that the first few days I will feel a lot of anxiety. I would like to receive advice on how to handle it better and take it more calmly and that can help me be efficient in the position. Thank you.
