A phrase first used in the Beatles song 'Ticket to ride' in which according to the book by Steve

John Lennon as a way to describe prostitutes who worked in the streets of Germany, these women acquired a card from medical authorities, which stated they were in good health. In this context the ticket is the medical card and the ride is the experience with the
prostitute, within this context the medical card is used as a prerequisite.
In modern times this phrase has been used by Mark Goldbridge to describe how
football fans are being exploited by footballers to sell merchandise and so on. Without the fans, no merchandise would be sold. In this context the fans are the ticket and the revenue from merchandise sales are the ride.
