I wanted to add that the money raised was being donated to Children's Specialized Hospital, but not sure where to put that or if I should put it at all.
Yes! In fact, I think you should make that the focus of the essay.
As the essay is now, it just shows that you were able to work at a sausage stand, which is not particularly impressive.
However, you DID demonstrate that you are an excellent writer. This is high quality writing, for sure. But I do not agree with the theme you chose. If you want to write about the sausage selling, you have to make it meaningful in some way. Did it give you some new insight into your own personality or values?
Make it so that this essay is about something more than just working at a sausage stand. The dialogue at the beginning and end do not help in any way. It is better to use your GREAT writing skill to express a meaningful theme.
