non paying customers .

Any business has undesireables, the key is to weed them out any way possible. The auto business was very frustrating due to the customers. I saw Richard Rawlings advising a guy on his new 'garage makeover" show that he should scour the neighborhood and let the closest businesses such as the convenience store know to send people to his garage when they ask about auto servise/tire /air etc. I immediately thought "thats wrong, you don't want every Tom, Dick, and harry off the street coming to your shop for service. There just isnt any $$$ in it.
