What are the daily responsibilites for owning a auto detail shop?
I think it would be easier to divide this up into 2 groups.
1) The daily responsibilities of owning any business. (Employees, scheduling, $$, handling customers, reviewing marketing plans, keeping the place clean, etc.)
2) Responsibilities about owning an auto detail shop (inventory, scheduling of services, training, quality control, etc.)
Brainstorm those ideas. Then (after you came up with some on your own...you'll be more prepared) contact a few detail shops and ask for the owner or manager. Explain you're doing a homework assignment and are researching this question. Most, if not all, you contact will probably be willing to help. Just realize it's often a fast paced business so don't take up too much of their time. :)
