Every day, people come and go from your restaurant. You see new faces and the regulars. Wouldn't it be great if you could find a way to get those new faces to return?
For years, restaurants around the world have used the "fish bowl" method to capture business cards. The idea being to offer a free lunch once a week to customers that drop their business card into the bowl.
What happens to all that valuable information on those cards once you give away that free lunch? You might have brought back one customer but what about all those other business cards?
