That's exactly how I see it too! I am someone who always pays on time, always settles debts immediately, and treats everyone fairly and compensates them accordingly. But I also expect that from the other side. Yes, the landscape gardener also works for companies, municipalities, and cities where he probably only deals with net prices. But why should I now swallow the bitter pill because he gives me (even if probably unconsciously) the wrong prices?
With my heating (the thread is now starting to look Shiny-suspicious), the heating engineer also firmly claims to have done everything right, although I have learned from several sources (including professionals) that the installation spacing is too wide. If he would admit that he did a shitty job, he would already be highly regarded by me. But since he is stubborn and still claims, even after I’ve shown him my photos, that he specifically installed underfloor heating and that everything is fine, I’m slowly getting pissed off! I am increasingly refusing to pay for other people’s mistakes, who drive around in Porsches and Maseratis.
