Most places in palm beach county (advance auto, auto zone, etc) won't take your empty containers anymore, and they make you dump them yourselves, I just empty them and take them back with me and put then in the recycling bin at home.
When I worked at advance auto we wouldn't let the customers dump it, when I lived in pa people used to bring in 5 gallon buckets of hydraulic oil, those are such a pain to dump into the hole on the top of the tank
