I usually make a cake when we get any work done. A couple of years ago I nearly killed a painter and decorator. He had been at our house for a few days decorating the hall,stairs and landing and had sampled several different cakes during this time. On the last day he had a large piece of fruit cake. Swallowing the last mouthful he said "was there pineapple in this?". Of course there was - it turned out he was allergic to pineapple in a big way. It is funny now but at the time he was very poorly and had to take a couple of tablets and make sure he dint have any reaction. All afternoon I was waiting for a thud on the stairs as he fell of his ladder.
