previous jobs on sf85p

Hello, currently filling out the forms for a public trust clearance, and I have some questions about previous jobs. I worked 2 jobs during high school (fast food) that were extremely short. Combined I probably worked 2 months total at the jobs. I don’t remember my managers name for either, and the restaurants wont pick up the phone. What would be a good reference? Could I use my friend that knew I worked there? thanks.

Just put that you don’t recall any supervisor information.
