Poxy client has not paid. It's only £45 but to someone as poor as me that's a noticeable dent in the month's budget. Is there anything I can threaten him with to make him pay? I don't want him just to get away with ignoring me, I want to annoy and worry him a bit so it's got to be a threat I can back up.
(NO, I am absolutely not talking about doing anything illegal).
