I have a house i rent out to holiday makers. I used to live in it so know my neighbours well. One neighbour has painted the back wall of my house when she was doing hers. She asked me if i wanted it done first and i was glad to accept.
The paint cost was £68 but i wanted to add something on for her time and effort. She has done a splendid job. What would seem reasonable? I know she will not be expecting anything and will be a bit cross/mortified if i give her too much. Would rounding it up to £100 be okay?
