Using a Private Process Server - Any extra perks?

Using a private process server has extra perks.  I still remember the first time I got called to testify in Court.  I had served a person in Davidson County on a petition, and the attorney who had hired me had asked me to keep my eyes open because it was a very contested matter regarding support and the lawyer thought that the person was lying about their income earning abilities.  I went out and served the legal papers at the person's work and I looked around.  The person was working hard with a lot of employees, and even chatted with me a bit.  By showing interest, I found out a lot of information that they had been hiding from the other attorney and possibly even their own attorney.  I put all of this in a document for the attorney and she was very pleased.  

When it came to have a trial, I got a call from the attorney asking to testify.  I got to testify in Court about all the information I had witnessed with regards to the person working and what they had said about income.  There is no way any of that information would have been discovered had that attorney served the documents with the sheriff.  The attorney to this day five years later still uses Holton Services to serve private process in Davidson County and other surrounding counties in Tennessee, and is a regular client.  The client was also pleased, as I was told that my testimony about what I witnessed while serving was the turning point in the case. The small amount for the private process, and the trial time and testimony fee, helped make sure that client got a judgment exceeding five figures and was an excellent perk of using a private process server to serve process for them in Middle Tennessee.
