We're having lunch in a busy cafe (me, DH, two dcs). We ordered a main meal each plus two sides of chips to share. All the chips were soon polished off. On the next table was a woman and her son. She ordered chips for him, but when they arrived he only ate a couple and refused the rest. They left soon afterwards. My DS wanted more chips, so I gave him the (largely untouched) portion from that table. DH was aghast but my reasoning was that the waiter was only going to bin them anyway - why waste food? Was I BU?
