The bail in is a scary proposition, isn't it? I am not sure of the laws in Finland on this, but I suspect it is heading the same way, if not already.
Your can story reminded me of about 15 years ago when my ex and I were saving for a trip to Australia. We already had tickets, but for spending money, we decided to only use cash for six months and all change, went into a jar. It ended up being over 1000€ worth. Not bad!
