If I'm paying for people to parasail then why can't I just ride for free?

We love to be able to accommodate everyone but we are in the business of parasailing and not boat rides.   All of our expenses as a parasail operation are much higher than a standard tour boat giving boat rides and we just can’t make any money reserving for riders.  At 30 bucks we are still the cheapest boat ride in town and many of our customers tell us it's worth the $85 we charge for parasailing just to ride on the boat.
