The Triflers(1920)

Janet Randall, a department store clerk who longs for a fling at high society, ignores the love of the poor but honest Dan Cassidy. When vacation time comes, Janet goes to a fashionable hotel and there meets her idol, society favorite Monte Moreville. Upon requesting the bill at the end of four days, Janet discovers that the tariff is more than she can afford, and Monte comes to her rescue by offering to bail her out. In exchange, Janet must pose as his wife to fend off a woman who is threatening a breach of promise suit.
