Another possible origin is double Dutch, the jump-rope variation in which partners simultaneously participate.A folk etymology is that the "Dutch" reference derives from Dutch Schultz, a New York gangster of the late 1920s to mid-1930s, who may have used dutching to profit from gambling on horseracing, though his nickname derives from Deutsch ('German'), in reference to his German-Jewish background.In North America, the practice of "going Dutch" is often related to specific situations or events.During meals such as birthdays, first-dates or company business lunches, an expectation develops based on social traditions, personal income, and the strength of relationship between the parties.For romantic dates, the traditional practice is that the man pays.In a business meeting, the hosting party usually pays for all – it is considered rude not to do so.In Urdu, the practice is called apna apna, which means 'each his own'.
This is referred to in the Spanish language as pagar a la catalana ('to pay as the Catalans [do]', 'to pay Catalan-style').
One suggestion is that the phrase "going Dutch" originates from the concept of a Dutch door, with an upper and lower half that can be opened independently.
The Oxford English Dictionary connects "go Dutch" and "Dutch treat" to other phrases which have "an opprobrious or derisive application, largely due to the rivalry and enmity between the English and Dutch in the 17th century", the period of the Anglo-Dutch Wars. The gambling term "dutching" may be related to "go Dutch", as it describes a system that shares stakes across a number of bets.
In Greece, the practice is colloquially called refené.
In Italy the practice is referred to as "alla romana".
