The only take out place we leave a tip is the local mom and pop pizza joint. Actually it is just a pop joint, as mama is no longer with us. We have patronized this establishment for over 25 years and it is staffed by mostly high school students, and both of my sons worked there when they were in high school. With that in mind I have watched many teenagers get thier first start in the real world of employment while they are saving for college, cars, insurance, school supplies and other teenage stuff etc., or working to help support their families. So I figure a extra fiver isn’t going to hurt me, and it is appreciated by the recipients. And as a bonus when I order a pizza, I know it is going to be right, and maybe they will put on extra toppings. And more importantly I usually get a warm welcome from these kids. That is worth the fiver alone.
