I was intrigued enough to go and find it - a picture of a roast being sliced. It's meat. It gets cooked and sliced and eaten. There are also scones (veggie?) so perhaps that just leaves vegans unoffended.
Anyone who is a vegetarian should avoid completely clicking the Ad which could result in a spate of meat Ads following them in all sections of AB..I don't use Ad Block, but just ignore the Ads because I once clicked one for KIA Cars and now they appear everywhere in AB; sometimes four to a page.
I can't find the thread where I think the Ed said that it had something to do with Google targeting us.
