Reminds me of when I was young I did a volunteer session at soup kitchen for the needy. After dinner was served we went around and collected the used dinnerware from the patrons there. I went to one lady and took her plate, upon which she angrily scoffed at me "I can take my own plate up! I am not one of the guests here!". She was in fact one of the guests.
