“Get Back Here and Give Me My Gratuity!”
Imagine not having enough cash to pay for a gratuity which a fellow dining partner who paid the bill failed to leave to the waitperson, so a cup of coffee had to be purchased and charged to a credit card with a large tip to atone for that oversight.
Have you ever seen suitcases take flight all by themselves because of an irate taxi cab driver stiffed out of a tip who served as their launch pad?
A waitperson complains that a 10% gratuity is not sufficient enough after delivering what was perceived by the patrons to be poor service.
We are willing to bet the ones who leave either no tip or a gratuity so incredibly small — think one penny or so — for their perception of poor service probably would be the most likely people to raise their hands in response to that question.
