My 19 year old son is working at a nice college restaurant and had been waiting tables but is now hosting only. The mother of the restaurant owner told me it was because of his "disability" and elaborated on why he couldn't do the job. My son is over 18 and he needs to advocate for himself but I want to provide him some info to help. Does anyone know of modifications he could use to handle carrying drinks or trays. The issue is with supination in his left arm. I'm a special ed teacher and am always trying to come up with ideas to make my students successful. It seems like there should be something that could be used to help him. Thanks in advance.
