Whilst Rob has pointed out the pitfalls to Geoff even though he has won the case, the damage to Mr Wood's business, I suspect, will be pretty substantial as this isn't the only place this has been posted. A disagreement with a customer over a fairly minor amount of money can have substantial consequences and if Mr Woods is folly enough to see it through court, lose and still not pay up, then frankly he deserves all he gets. Unfortunately for Geoff it's his loss that will stop others ending up with the same fate.
