I have gotten many gallons of Coleman fuel, Coleman stoves, lanterns, chainsaw bar oil, WD-40, Propane tanks of all sizes and even ammo. I check everything to make sure it is not some miss marked container
My city does not do this but I have a good friend who lives in Madison, Wisconsin and they have a center that takes stuff in "hazardous materials" or some such, and he has done the exact same thing. He has gallons and gallons of Coleman fuel, lacquer thinner and other solvents like Acetone etc.....he has also gotten a little ammo but they are kinda hinky about that. It's a pretty liberal town.
