My best effort ever was when I was acting for a construction company in Derby.
They'd bought the old greyhound stadium to build a 200 home housing estate and, before they could start, the Gypsies moved in with dozens of 4x4's, etc. They engaged the police, courts, council & bailiffs but no one could shift them.
I was engaged to shift them and I asked for £30,000 which I thought was outrageous but they snapped my hands off.
I turned up with 4 massive concrete lorries, the lads from the night club and the big lads from the gym, all in high vis & hard hats.
We started to tip concrete onto the only entrance thereby blocking them in permanently.
When the 'King of the Gypsies' came out to start the argument I nearly messed my pants ...... but I stood my ground because all the lads were watching and taking their line form me. I told Ginger John that we had to close the entrance due to Health & Safety issues and gave him 2 hours to get all the vehicles & caravans out.
They were all gone in 25 minutes after months of court battles and fruitless bailiff visits.
What they hadn't realised was that the one thing travellers hate more than being asked to move was being told not to.
