You can grant them, but, if your at max 99% happiness there is no need to collect the Wish once the task is complete. Let them float around and only click them if your happiness is less than 95% (Each Wish in the last happiness tier is worth 4%).

With the happiness from chests you can generally keep your happiness up and won't need to collect your wishes. You can usually have around 5-10 floating around your Kingdom at one time.
