In Robinson v Balmain New Ferry [1910] AC 295 the claimant paid one penny to cross the river by ferry. At the entrance was a sign stating that the penny was payable at the terminal to cross the river and again after a return journey. The claimant passed through the turnstile and then having missed the ferry he sought to exit. However, he refused to pay the further penny required so the turnstile operator refused to allow him to exit. There was no false imprisonment since:

…the claimant was merely called upon to leave the wharf in the way in which he contracted to leave it. There is no law requiring the defendants to make exit from their premises gratuitous to people who come there upon a definite contract which involves their leaving the wharf by another way.
