Bob arrives at Alice's place and here is their dialogue:
Alice: Hello Bob, thank you for coming. I wanted to show you the problem I told you about on the phone.
Bob: Hello Alice. Yes, show me that.
Alice: Look here, on this wall. Since the end of the work, this stain has been visible. I find that it stands out a lot, especially with the light from the window.
Bob: I see it. To me, it's not a paint defect. It looks more like rising damp or an old mark reappearing through the surface.
Alice: However, this stain was not visible before the work. It appeared right after your intervention.
Bob: It may not have been visible because the old paint masked it more. I applied the paint in accordance with the estimate.
Alice: I understand your point of view, but the final result is not satisfactory. I paid to have a restored room, and today this stain immediately catches the eye.
Bob: I understand your dissatisfaction. For my part, I do not believe I am responsible for the condition of the wall itself.
Alice: What do you suggest then?
Bob: I can come back to apply a new finish coat commercially, but I cannot guarantee that the stain will not reappear.
Alice: A simple extra layer doesn't seem sufficient to me. I would like the problem to be dealt with definitively.
Bob: For a complete treatment, it would probably be necessary to strip the area, apply a specific product, and then repaint. This represents additional work that was not included in the estimate.
Alice: However, I believe that this result should be included in your service.
Bob: I do not share this analysis. For me, the quote was for painting the bedroom, not for repairing a substrate defect.
Alice: I understand your position, but I do not wish to pay more to get a correct result.
Bob: And for my part, I cannot perform additional work for free for which I do not consider myself responsible.
Alice: So we disagree on the origin of the problem and who should cover the cost of the repairs.
Bob: Yes, unfortunately.
Alice: That is a pity. I was hoping we would find a solution today.
Bob: Me too. If you change your mind about my proposal, please feel free to contact me.
Alice: Alright. Thanks for coming anyway.
Bob: Thank you for having me. Have a good day, Alice.
Alice: Good day, Bob.
