Well, then, I wonder what they will comment after seeing Japan's traditional unmanned shops? I am not talking about high-tech shops with robots as sales staff... we would need ten more years before such unmanned shops open. I am talking about a very much primitive shop like the one in the photo below:
It is written in Japanese "this is where you put money". Generally the old farmer brings in his produce around 6:00 am. Then he won't come back until the evening to collect the money.
As an English-French-speaking tour guide, I am influenced by the American and European ways of seeing things. So I worry for him. "Aren't there any dishonest guys who pay less or even pay nothing?" "Aren't there much worse guys who just grab the piggy bank and go away?"
Last year, my wife and I visited Aomori prefecture in apple harvest season. Aomori prefecture produces more than 50% of apples produced in Japan. We enjoyed driving along local farming roads seeing the whole stretches of land with apple trees heavy with fruits.
