Loved the "Wakey Wakey", I think my adults would be teasing you mercilessly over that! They would rather you, in the time you spent providing "concierge" service a) get a shower or b) start the coffee.
Mustering duty falls on our SPL, who by the average age they get elected is up an moving in time to perform it in his own style. If we're lucky, he has a bugler.
The wakey wakey was a bit of a one off for the sake of the film. Normally if they aren't moving I sing at them. Loudly. And badly. My vocal range has approximately two notes. Which are out of key with each other. It's a truly horrible noise
On a more serious note though it does highlight a big difference between us and you. Scouts here runs to 14 and a half rather than 18. It does mean that there does always need to be that bit more adult in put on anything they get up to. It doesn't mean the PLs don't get responsibility, they certainly do, but the average level of maturity and experience will always be that much lower meaning we do have to support and prod them in the right direction that much more. And some times that does mean kicking them out of bed!
On top of that at the moment I have quite a young troop at the moment. I lost 9 x 14 year olds to explorers at Easter. That only exasperates it at the moment! They are getting there though.
