California has tens of thousands of local businesses, and yet only one official office to police them? Lets say I get ripped off by a restaurant, store, or local company (and I find out later after looking at my CC bill), what recourse do I have? Call the police? What are they going to do? Do they even handle financial fraud? File with the attorney general of California? Is his office really going to look into my issue? Do we just assume all companies are law-abiding? This doesn't make sense to me. (I know you can call your CC company and dispute the charge, but that doesn't punish the company doing it, except maybe not crediting them that one charge, that is not a deterrent to overcharge your customers, there should be some form of punishment by a government authority)
