Well of course voters accept this vernacular, slang usage! It works great! March into the principal's office, slam your fist down on the desk, and demand your free public schools for your kid. Stagger into the E.R., slam your fist down on the triage nurse's desk, and demand your free health care!

It works great at the ballot box too! "Vote now for your free stuff! Everybody gets more free stuff when they vote for me! Support the bill for free stuff!" Because if you called it "using other people's money", then the Ghost of Margaret Thatcher would arise and invade Puerto Rico.
