I used to work for an pizza pub in Natchioches, LA. I've had a great many experiences. One I can share involves me delivering to a very posh neighborhood. My normal vehicle was in the shop so I ended up having to drive an old, beat up Toyota truck that belonged to a friend that evening. I found the address, pulled up the steep driveway, and used the emergency brake because I decided to leave the truck running. I got to the door, delivered the pizza to a beautiful woman who took it graciously but seemed distracted by something behind me. To my amazement, she gave me a $20 dollar bill as a tip, still distracted by something behind me, and said that I may need the money. I turned to discover my truck rolling down the driveway!
Apparently, the emergency brake was not so reliable, the stupid truck. I pursued my truck with more swiftness that I thought I was capable of, but I could not stop it from going into the street and with traffic. Luckily, the cars saw it and slowed. It must have been a site to see a truck roll by with a guy chasing it. My troubles were not over. The truck cleared the street without injury but was heading directly for a very nice house, one I could never hope to afford. But fate was kind as I was able to catch up with the truck, jump in, and slam on the brake less than five feet from the house. Luckily, the owner of the nice house didn't notice so I simply left. I'm thankful that things could have been worse.
