yeah you can file a small claim against them. you'll have lots of papers to fill in, court fees to pay and will have to take at least half a day off work. you will probably win the case but then you will need to try to enforce the 10 pound owing. you could employ a bailiff, although that might set you back a few quid only for them to tell you they cant find the guy. now that you have spent a few hundred quid on top of your lost wages you might be wondering.... was it worth it all? take some comfort in knowing that you gave a good laugh to the judge, the court clerk who processed your claim, the bailiffs office and if he ever finds out about it, the customer.
