going dutch

"Going Dutch" (sometimes written with lower-case dutch) is a term that indicates that each person participating in a paid activity covers their own expenses, rather than any one person in the group defraying the cost for the entire group. The term stems from restaurant dining etiquette in the Western world, where each person pays for their meal. It is also called Dutch date, Dutch treat (the oldest form, a pejorative), and doing Dutch.
A derivative is "sharing Dutch", having a joint ownership of luxury goods. For example: four people share the ownership of a plane, boat, car, or any other sharable high-end product. This in order to minimize cost, sharing the same passion for that particular product and to have the maximum usage of this product.
