Avis has a wonderful marketing arsenal in their agencies. One of those is using the maps at their benefits.
At the beginning of this post, you have an entire map of France and a local map of Paris. As I worked at one of the train station in the French capital, you cannot imagine the number of people who came by, only to ask for a map or for directions. They got one for free with Avis written all over it (and with a big smile from me). Maybe next time when they think of renting a car, they will think Avis (and how friendly they were!).
