Reddit user jfastman took to the site on Tuesday to describe and display what has to be one of the cheapest tips of all time: $10 for a whopping $1,453.95 bill. That's not even a 1 percent tip! The tip, which the Reddit user says his friend received in exchange for 85 pizzas, can be seen if you just scroll down a bit.
So how much should you tip the pizza delivery guy? 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.
