January 2014: A false-advertising class-action lawsuit was filed against Uber, the transportation services mobile app company, for allegedly deceptively representing that it automatically adds 20% to the fare as a gratuity for the driver when, according to the plaintiffs, the company keeps a portion of this 20% gratuity for a profit. (Plaintiffs filed an amended complaint in April 2014.) (Ehret et al v. Uber Technologies, Inc., Case No. 14-cv-00113, N.D. Cal.).
