Curious

Why is a twin billing a double feature at the movies but a double header at the ball park?  Double feature is related to feature film, but where does header come from?  You may have guessed that twin billings was a crossword puzzle clue and I filled in the wrong answer first.  I always use pencil.

Minimum Wage

Received by e-mail:
"No, volunteering does not violate minimum wage law. If there is no wage and no expectation of a wage, then how can a minimum wage apply? "

I'm sure he is correct about the letter of the law.  That means I can work for the minimum wage or for free but for nothing in between.  Does that make sense?

The minimum-wage law is generally considered to be a restriction on employers but it is also a restriction on would-be employees.  This keeps some people, especially young people without experience, out of the work force.  This can't be good.

Minimum Wage Question

Does volunteer work violate minimum wage laws?  If not, why not?
