ALWAYS carry spare change in your car if you’re going to drive. No matter where you are or at what time, if you’re backing out of a spot there will be someone rushing in behind you to “direct” traffic and “assist” you in clearing the way for your car, and you have to tip them.

You should also keep the change in case you decide to buy something from one of the many street vendors selling random things on the side of the road to drivers.
