What the hell is going on with shops?

People forget the cost of running a business. I give someone a price of $300 to detail their car and they look at me like I have 6 heads. 8 hours of work, 1 mill. dollars of Insurance, Rent, lights, heat, phone and internet, marketing, shop supplies all need to be paid before I split profits with my partner. Out of that $300 Im lucky to take home $75. If I had employees I would be in the red.
