LOL i have work and deliered for a local chain, dominos, and papa johns, and trust me, drivers now people who tip and people who dont. When i wroked for papa johns we delievered from everything to trailer parks to Gated Rich Communitys, and each are different, I had one guy who ordered $40 worth of food and gave me $60 and told me to keep the change! but i would also get people who would order $60-70 and only tip a $1.

Every driver at our store knew address that wouldnt tip and would avoid them to get a house that tipped! So if you people who dont tip very much all the time always wonder why your food takes forever!
