The crisp potato chips

It's widely disputed, but an American cook called George Crum is held by many to have been the inventor of the crisp. It's said that one day on 1853, a customer complained that Crum's chips were too thick, so Crum decided to take his revenge by making them inedible. He sliced them thinly, baked them to a crisp and covered them with salt. The customer loved them. Well,on this  I would rather say that this is the best example to show that love takes birth out of hatred ! :-p
