benefit supper
A community-sponsored meal that's intended to raise funds through free-will donations, but which in the end often merely "benefits" multitudes of freeloaders who just come for the free food, and then quietly leave again without dropping any money in the donations-cup.
If towns would not charge such outrageous sums in properly-taxes, there might likely be fewer "abusers" of benefit suppers, since there would be fewer cash-strapped folks who would sulkily feel that they were "owed" free meals due to their already having shelled out grossly-excessive amounts for their property-taxes.
