What are some Community service ideas for spoiled teens?

Pardon me, i do not mean to offend anyone by using the term spoiled in such a harsh context it's just that unfortunately it describes these teens I work with to a 'T'. A few months ago I got us to volunteer at a soup kitchen on the poorer, rural outskirts of our town (Greenwich, CT) unfortunately, it did not go well and I am afraid to admit that the behavior and comments that some of the guests at the soup kitchen made, made many feel uncomfortable and turned off of the organic self gratifying feeling that community service usually brings to the volunteers and helping others in general. I need a few ideas for this month (January) that would show the teens the true nature of community service that i know exists. Could you recommend a particular activity that could take place this month ( January) preferably indoors that the teens would be enthused in participating in?
