It's an agreeable idea to local small business owners.They eat & see Their Business ad right in front of everyone. Additionally,the customer's are mainly local people who need services performed.They see the local address,usually a discount included,and simply tear out or ask for a clean mat to take home.And,the puzzles keep their focus while waiting on the food.Good return rates.I work with most of my customers to allow continued advertising throughout the year.... My little ideas have been constantly upgraded to enhance visibilty.This is how I have personally made a living for the past 17 years doing just this.Write me for more [email protected], Mike
