Reddit user jfastman took to the site to post a photo of a $1,453.95 bill... and a measly $10 tip. (FYI, that's not even one percent.) He says that his friend received ten bucks in exchange for delivering 85 pies. The post sparked a flurry of conversation on proper tipping etiquette. Mike Lynn, associate professor of consumer behavior at the Cornell Hotel School, suggested to CNNMoney that pizza delivery workers should be tipped a minimum of $2 per pizza. According to this math, the delivery worker in question should have gotten a $170 tip -- again, at a minimum.
