I was in a stinking foundry the other day that made stuff for land rover and others and I asked the guy how they make it work and he said each machine in there could work without breakdown for 120 a week so we sell hours to companies and when they're sold that's it. So if a firm cancels an order or whatever the sales crew go out and sell those hours to some one else...as it was they are flat out cash rich with no worries at all...could you imagine?...
