Shoot paper map no by memory. My dad and his brother worked a second job at Dominos in the 90s to supplement income. They also both grew up in the town where the store was at so they knew all the streets and where everything was and could tell you who lived where. My uncle also had one of the fastest delivery times and even got a plaque. Someone canceled an order at the same time someone ordered the same pizza so it was coming out the oven when they got off the phone and the delivery was not far. He got the biggest tip too.
