In that case, the term “weights and measures“ covers all devices used to measure. For example, in the food sector, there are scales pretty much everywhere; the butcher has his scales, each cashier has a scale. There is a lot of money involved here, because these deviations can really add up. I believe that people spend more money on average on groceries than on gasoline. So how do things look as far as that sector is concerned?
