"When I was catering, we often would package up a meal for 10-15 people and drop it off a local law firm, real estate office, etc to 'introduce' ourselves. As a result, when they need catering we were in the door... most of the time. Also, on Secretarys' day ("Administrative Assistants' day") we would blanket our current customers and potential customers with something special for the Secretarys... like a little choclate cake or chocolate covered strawberries, etc. This isn't earth-shattering marketing, but it was effective and really didn't cost nearly as much as print or radio advertising."
