Some people are throwing food at each other in the cafeteria.
DON'T DO IT!
When food is thrown in a cafeteria, it makes a large mess for the janitors to clean up. Like the Golden Rule says, 'Do unto others as you would like them do unto you.' By throwing food you are creating a problem for both the janitors (Who have enough work already cleaning up ACCIDENTAL spills) and the person you are throwing food at. You might not mind getting your clothes dirty- BUT SOME PEOPLE DO!
Be considerate, and don't throw food!
