Persistence Does Not Always Pay, or Even Make Sense

My cell phone is a business phone.  Since we recently moved to a different city, I have avoided taking on new customers in my previous location.  That, combined with the excessive sales calls that business lines often get, leads me to screen my calls.  If I do not recognize the number (current customer or friend), I do not answer the phone.

It is the time of year that the local Yellow Pages (or some variant) is selling ads.  I have 14 calls that I have not answered from them.  Now, I appreciate that good sales people have to be persistent, but how does one sell yellow page advertising to a business that does not answer its phone and has no location for customers to go to?

It will be interesting to see if the calls continue on Monday.
