The consumer is ultimately harmed if they cannot calculate how much of a certain foodstuff they are buying. I'd feel exactly the same with 'metric only' scales.
That's the best you can do? Seriously afleitch, I expect better from someone of your intellect. At best you can make the case for that being inconvenient, but to call that harm is completely ludicrous and you know it. I mean think about it - this woman runs a vegetable stall. How many recipes call for "2 kilograms of tomato and .5 kilograms of potato"? Recipes call for stuff like "2 medium sized tomatoes and half a potato". For ingredients that require precise measurements you'd generally use your own measuring instruments anyways. Those who actually require their vegetables to be bought in kilograms and pounds are probably going to be restaurants and the like who are going to buy in bulk anyways, meaning not from a roadside vegetable stall.
