Julian and Anna recently celebrated their 20th wedding anniversary. To properly celebrate this milestone, they decided to go on a holiday together to Bliss Island, a small exclusive, tropical island in the Whitsundays in Queensland. The brochure for Bliss Island shows white, sandy beaches, beautiful tropical vegetation and an amazing five start resort. The brochure also states “Bliss Island offers some of the best reef diving anywhere in the world, available all year round.” It also states that “visitors will enjoy some of the finest foods, prepared by some of the best chefs in Australia.” Pictured alongside this statement about food are several delicious looking cakes. Given that Anna and Julian are both keen divers and that Julian enjoys eating cake, the choice of venue for the holiday is easily made. When Julian phones to book the holiday, he speaks to Sandra who runs the resort. Julian asks Sandra “so how’s the diving?” and Sandra replies “It’s always brilliant here.” Julian also mentions that he enjoys cake and comments that he is really looking forward to eating lots of them when he gets there. Sandra says “the food here is really exceptional, I am sure you will love it.”
