* Mike Lynn, associate professor of consumer behavior at the Cornell Hotel
School suggests tipping pizza delivery folk a minimum of $2 per pizza. His
reasoning: Food delivery can be dangerous if delivering to crime-ridden
neighborhoods or driving in bad weather, etc. The Web site www.
tipthepizzaguy.com suggests the following: 15% for normal service, with a $2
minimum; 20% for excellent service; 10% or less for poor service; at least
10% for orders of $50 or more. Don't assume a delivery charge, if there is
one, goes to the pizza deliverer. Ask the person who takes your order.
