DH got called out today to repair a WC. The customer asked if "no fix no fee" so he said yes. He goes there, starts on the job, half-way through the woman says it's taking too long and she doesn't want to continue. DH points out that he might as well finish the job since she's going to pay for his 2 hours (£80), she says "no fix no fee". DH said he can fix the problem. She ain't paying. Just rant and rave at home or is it worth going to Small Claims for this. Thanks.
