"Going Dutch" is a term that indicates that each person participating in a group activity pays for himself, rather than any person paying for anyone else, particularly in a restaurant bill. It is also called Dutch date, Dutch treat and "doing Dutch".
One suggestion is that the phrase "going Dutch" originates from the concept of a Dutch door. Previously on farmhouses this consisted of two equal parts (Sullivan 2010).
A Dutch door (American English), or stable door (British English), or half door (Hiberno English), is a door divided horizontally in such a fashion that the bottom half may remain shut while the top half opens.
Help me connect the dots.
