TELEPHONE NEIGHBORS OF YOUR NEXT DAY'S CUSTOMERS. By using the city directory you can find out the telephone numbers of your customer's immediate neighbors. This directory has a reverse directory which lists all the neighbors on the block according to address, their names and their telephone numbers. You could call up everyone on the block in a matter of minutes! Mention that you are going to be doing Mrs. Brown's place down the block tomorrow and you could be glad to do her place as well. Both you and Mrs. Brown will receive our 'in the neighborhood' discount of $10.
