A tradesman is called out to fix an appliance... he attends, diagnoses the problem and has to come back on another occasion to fir new parts: is it right and fair that the minimum callout charge should be payable on both occasions, or would it be expected that the time for the second visit would roll on from the first?
Not having a 'go' here - just wondering what standard policy was!
