When you open the lid with cooked items on the warming rack i.e patties ect, the rack hangs over the back of the BBQ and the items drip all over the lid and drip out the back of the BBQ onto the deck making  grease stains etc on the deck, patio ect. Also, the side burner lid should have a warning on it when it is closed to state open before lighting and the burner knob be a different colour then the others. Burner was turned on by mistake and heated up and burned items sitting on the lid. Can you buy a replacement Lid for this?
