Appointment letter format for cafe employees - designations like cafe manager, water, and supervisors

I hope everyone is doing well. I am looking for an Appointment letter format for Cafe employees, designations like cafe manager, water, and supervisors. I also need a format for cafe Rules and regulations. I am working on a new project for a startup cafe in Bangalore, so I need expert help. It would be great if anyone could share any information.

Thanks and regards,
