My late mother (see picture above, taken in the 1960s) was averse to weighing machines.
When she visited the doctor and had to be weighed, she did not want to be told or in any other way infrormed of her weight.
Her dislike of weighing machines extended into the kitchen. There were no kitchen scales in our home. A good cook, she managed without them. However, she did use a conical measuring device made by the Tala company. This contains printed markings that allow the user to dispence known amounts of powdered ingredients such as, for example, flour, rice, and sugar.
Years after my mother died, I married a lady from India. She told me that in the olden days, professional cooks of Indian origin often measured out cooking ingredients by feel rather than using a weighing device. For example if a cake required an equal weight of egg and flour, the cook would hold the egg in one hand and estimate its weight by feel and then measure the required amount of flour, also assessing its weight be feel alone. I do not know whether my mother possessed this skill, but regardless of that she was widely recognised to have been a competent cook.
