no there is nothing like that but..... alot of drivers will remember houses that do not tip on a regular basis and adjust there route accordingly. When they have two orders and one person they know always tips well and someone that hardly ever tips, then the good tip is gonna be delivered first. As far as the delivery charge, that is built in for the people that don't tip, please don't assume the delivery charge is the tip. On the delivery charge at my store, the charge is 2.75 and the driver only get some of that. So just because there is a delivery charge don't assume that a tip should not be considered.
