I'm really amazed this can even be discussed. The OP stated a condition* to get the free chests he had worked for. A condition to get free loot. So the get the free loot you must satisfy the condition. Is that really hard to understand?
*I would not have phrased it the same way, probably more like "Quest done, 3 free chests. I'm looking for bauble and really need it. Help please." as suggested above. But the OP did the work and can set whatever conditions he wants; others can choose to join or not.
