Family Dollar complaint: stolen money

I had just cashed my check from work I stopped at Family Dollar to buy a things that I need it for my house like I always do. When I got back to my car all of my money was gone out my pocket. I went back in the store and told the manager I just dropped $1,000 in hundred dollar bills on the floor in the store and I know I had it because I’m usually paranoid about that much money and I had my hand on it in my pocket while I was in the store. The manager went to the back room for 5 minutes with another employee and then came back to me and told me he doesn’t have the password to the computer and there’s no way he can check the cameras and told me there’s nothing he can do. Are you kidding me? He’s the manager the computer or cameras and why was the other employee back there with him and why did it take 5 minutes for him to say that?
