Thanks SC, I'll look into them both.
250 quid X 40 candidates is 10K, less a bit for the hire of an unconditioned room in the height of summer, some burnt coffee and a bit for wheeling in a couple of 'guest' speakers and its a nice little earner. I certainly did not feel as though I had just benefited from nearly 10Ks worth of training when chucking-out time came on day two. More like a pointless tick in the box in the bizzarre game of ass covering that the UK is so good at.
