What do you think?

So yesterday our dart league hosted our annual tournament. Our dart league raises money and awareness to all cancers and helps people who need it like for driving and hotel expenses, treatment, etc. Well the group of girls who won it (4 team members-2 of which are on the league) ended up winning $480....they ended up each taking a $100 each and donating $80 back to the league. Just curious what everyone else would have done. I personally would have donated it all back. They’re entry fees for the tournament were only $25 ea. And for me the point of it is to have fun and raise money for a good cause.
