.
Dutch treat: An outing or date in which each person pays his or her own expenses. For example, Her parents agreed that she might date if it were a Dutch treat. The related expression go Dutch means "to go on a date with each person paying their own way," as in Students often elect to go Dutch. The first term dates from about 1870, and the variant from the early 1900s.

I am not sure, however, that the term relates directly to social behavior in Holland.
