I'll never understand why their attack against skimmers was to put a giant molded piece of plastic over the slot which doesn't even look like its attached to the rest of the machine anyway and can easily be removed of sheathed with a skimmer. Surely the correct attack would be to make the slot as flush and minimal as possible without indentation so to hide a skimmer the entire front of the machine would need to be faked.
