RM 50 on the street!?

It gave me a giggle when I read the 'question'. It had me thinking when is the last time I saw any money note on the street x_x Moreover its RM50..
Honestly if I found a RM50 note on the street, I would start thinking of what could I do with it first.
Will I be needing money on anything important especially stuffs that are related to my studies(books etc.)?

If yes :
I would take it and use it for anything important.

If no :
I would save it for future uses.
