Last year, talking to a fellow builder when out cycling, he had done a lot of work for his neighbour up the street, about a few weeks work, got paid ok and then went off on holiday for a week,just a uk week away, got home and a barrage of abuse from neighbour on the ansaphone, and a written letter of complaint about all the faults.
The letter finished off by stating he the neighbour wasnt happy about paying for the builders holiday.
Always best to avoid doing bigger jobs for neighbours and relatives.
