I had an elderly Aunt and Uncle who really used to do this, they used to go to the pictures, buy a bar of Cadburys Whole nut, she would suck the chocolate off the nuts and pass them to him to eat, as she didn't like them! Yuk !
That is actually true. I used to visit an old lady (toothless) who gave me a bag of hazelnuts every so often. It wasn't until one day she said 'my neighbour Rene is poorly she hasn't been able to get to the shops lately. She would always bring me a bar of nut chocolate, I didn't have the heart to tell her I can't do with the nuts, so you won't be getting any for a while'. Ho hum. Glad I didn't eat any they always looked a bit gnawed at. It is now a family joke about Gladys's nuts.
