It is so very sad to say that there are people who are so very abusive. One day when I was working in some of the canteen, I saw more than five boys eating and laughing each other. For the first that I saw them, I also laughed but when I saw them clearly, I am shocked that they laughed each other because of the sauce. I'm so very busy in cleaning, so what I did was to never mind them. When I finished to cleaned. I came to the table where the five boys was ate. The five boys was already left out. I feel anger when I saw the sauce that was was wasted ( as you seen in the left side). I don't have any choice, but to take a picture on the sauce that wasted. I feel anger and sad that there people who do like this. Maybe they have more sauce in their house or kitchen. Maybe they are rich people, but if you are rich man, can you do
