You are stuck in traffic, arrive late for check-in and need to move to the front of the queue: Could I go in front, please? My connecting flight leaves in a few minutes.
In the story you have a cow with you that you feed with dates (could), an ostrich egg on its back (I) and a go-kart carrying a man who used to fight at the front (go in front). At the head of the queue stands a police officer reading (please), and you hand him a lily of the valley (my).
