That is exactly the problem George. When you stick the fork in there to dislodge the toast you can energize the whole case. If you have the GFCI it should trip if the user is in the fault path to ground. I understand in a stick built house with a vinyl floor there may not be an effective ground path without the plumbing (that might be plastic anyway) but here we have slab on grade with terrazzo or tile floors and that is an excellent ground path. I suppose if you always wear shoes it is not a problem but the first night in this house I found the defective ground electrode system when I touched the cook top (among other things). I am not sure exactly what the problem was but it sure woke me up.
The next day I was putting in GFCIs, tightening up stuff in the panel and driving new rods.
