Finding the source of the problem

James didn't complain and get frustrated at first, he was quicker to move and decide what to do. He then went to various parts of the factory, summoned the plant's mechanical engineers and the factory's team of laboratory testers. He made an impromptu inspection of the factory. Although not monitored and known by the police, at least James wanted to make sure beforehand whether the mistake was sabotage from outside the factory or something was wrong from inside the factory.

 The tank containing the drink, the packaging area, the laboratory, the materials used in the brewing, were all examined by James one by one. So carefully James checked everything one by one. James didn't want to miss anything, it was better for him to know beforehand and admit his mistake than to be found out by outsiders and increasingly blamed by the public.

 "Apparently this is the cause of the problem," said James. He found something.
