Cheating. I ordered Passion fruit and Lemonade, instead got Passion Fruit and Sprite. Did they think as the customer would not find out that they were cheating and charhinging for Passion Fruit and Lemomade. Please be aware

Yesterday my colleagues and I went for our end of year lunch to Ocean Basket Plumstead. Two of us ordered Passion Fruit and Lemomande. When the waiter arrived with the drinks it was already mixed and had no fizz. and very sweet. I know exactly how it must taste. I called the waiter to ask him about the drink, but he didn't want to answer me. I told him that this was not the real deal. When we left I saw a bottle of Sprite where the drinks were and that was exactly what I needed to see. They mixed the drink with Sprite that was not chilled and no fizz. I wonder how long this Sprite was open. They charged on the till slip Passion Fruit and Lemomade instead of Passion Fruits and a glass of Sprite
