Legalised robbery
We have a nice big oak tree in our front garden, here in 'Sunny' Bournemouth, which needs its branches trimming every year, however, because it has a tree preservation order placed upon it, I have to apply to the council for permission to do this.
The permission costs £160 (plus the additional cost of hiring someone to actually do the job) and has a short expiry date, meaning that every time we need our tree trimmed, it's another £160 for yet another permission slip (because, you know, trees grow, right?).
Easy money, eh?
