In Hong Kong I was impressed that I could check-in for my flight at the Central train station, and my bags went all the way through. What a good idea.
Here in Lund, in Southern Sweden, it appears that you can deposit your used recyclables at a hole-in-the-wall within a supermarket; you get a refund; or your press a button to give the refund to a charity. What a good idea. Nearly as good as a federal law prohibiting charging for university tuition. Brilliant.
Not sure about calling a chocolate 'plopp', however.
