Besides being frowned upon in those contexts in which the protocol rules, having to tilt the plate to finish what remains of a delicious soup or vegetable cream may even become frustrating. However much you are set on, you can never clean completely the plate unless you mopped up with bread, of course. But this option is disliked by the manuals of good manners. The solution to this problem was patented 12 years ago by Claus Roeting, the manager of CRIMEX GmbH, a German company engaged in marketing of promotional products. Thanks to his inventor´s soul, he designed a sloped bottom plate from which you can make the most of the last drop of soup. This invention was a massive success making the sale of hundreds of thousands of units. However, his creation had a major drawback: the impossibility of stacking it broke its introduction on the market. “When stacking three or four plates or so, the result was a tower of Pisa,” says Ramón López Mera, Galician product designer, who managed to round the plate for soup lovers.
