The more people you have calling the SPCA or humane society the better. Take pictures if you can. We had a terrible store here in Vancouver (one of many) and we just piled in there each of us on our own personal time, to view, take pictures, lodge complaints, and in one case purchase the dying animal in order to save it's life. We never managed to get them shut down but the local SPCA did make several trips there and continue to do so.
I do however agree with Chuck and Jenn in being proactive and appling for a job there. Influence and knowlege from within is a great tool in educating the uneducated.
