Answer:
Saul us using a visual communication.
Explanation:
In communication, the use of drawings, photographs, sketches to pass and/or receive messages are referred to as visual communication.
In Saul's case, whenever he draws an item (say apple; for instance), the attendant would understand what he meant and gives him an apple.
This kind of communication may be a little bit difficult and time consuming but until he finds a better way to communicate, he's left with little choice.
