Those are pretty sad examples I must say, but:
One time as I came out of a Vet with a baby lamb a woman asked me what kind of dog I had as it had unique fur?
Some PETA people protesting front of a
Milk case with signs that read, "Save the Cows?"...jeesh I had no ideas you killed cows for the milk?
An animal welfare group showed a
video of a farmer moving a dead cow by a tractor and were horrified. Let me ask you, how else is a farmer going to move a 2000 pound animal...by dragging it out by hand?
A woman wrote in complaining about farmers killing animals and asked why don't we buy our meat from the grocery store like she does?
I could go on, but with only 1/2 a percent of the population (1 out of 200 people) being farmers, there is a major disconnect from where food comes from today.
As for weights and measures, that is really easy to explain; times are changing. I have cut
wood all my life, am a certified logger and everything, but I have always dealt in cords of wood. Today the wood market has changed to tons. It is hard for me to convert from cords to tons after years of logging. It is conceivable to think that apples would now be sold by the hundred weight instead of by the bushel.
I cannot defend the sheep expert though!
