Nah, the owner wants to block scrappers.
If a taxi company keeps getting screwed over by patrons of a given restaurant, the company should stop providing service for said patrons, seek compensation directly from the people who require their service (the restaurant), or seek legal action against either the patrons or the restaurant.
Demanding otherwise is just naive.
You do have the option of not using a service that uses recaptcha. Nobody is forcing you to fill them out, you are making the choice to do it because you want the service the site owner is providing, and the site owner wants recaptcha.
