Not unless you have a work permit, probably not.
Yes
Florida allows you to hire as young as 14. It would be up to the hiring manager and Panera policy if a 15 year could be employed. Some other businesses in the area such as Publix hire at 14.
I would call the store or stop by Panera's to ask them directly. I haven't any idea what the age is or if they need working papers at age 15yrs.
