You think that marketing is saying yes to the next salesperson from XYZ (flyer/magazine/radio/whatever).
You agree to their pitch because you think you will get more business.
Your reason is right, your actions are wrong.
You reluctantly hand over a few hundred or a few thousand dollars each month.
Then you hope and pray that you get enough new business to pay for the cost of the ad.
(Plink, there goes another penny in the wishing well)
You get a few new customers and repeat the process over and over and over again.
