Recently, I paid two guys $150 to cary 4 tonnes of gravel up some stairs into my garden and level it. I figured it was a days work for the two of them, and that the price as reasonable. But then, they ran the whole time, and did it in half the time I had estimated for the job. And emotionally, I felt really ripped off, because I was paying twice the going rate for workers in my country. But WHY SHOULD I FEEL RIPPED OFF???? It is wrong to feel ripped off in such a situation. Their doing it quickly saved me time and stress as well.
