There are goods or things that must be weighed, not to scale them would mean cheating. Although not everything needs to be scaled but a scale helps in making accurate measurements.
There was this time I went to buy chicken, it was supposed to be scaled (this was the usual custom). But somehow the woman did not scale it, I wondered why but I said nothing. I watched her with much interest trying to figure out the stunt she was about to pull. But in the end, what I bought was to my favour. She did not use the scale and it added more to what I wanted to buy. I had to measure it myself when I got home to confirm if she cheated me, and as it turns out I had more than I bargained for.
The scale helps us and make things much more easier. Not to scale can lead to an error, so I say it is good to scale.
