Sorry, but once you bring "spirituality" and things like it (psychics, demonologists, etc), you totally flush your credibility down the toilet with people like me. People who are skeptical, yet believe something is out there.
"Blessing" houses, performing exorcisms and things such as those have *never* proven effective at all. The "investigative" methods used by PRS are amateur at best. I've seen grade-school children better prepared to debunk claims and perform a real investigation much better than these guys have.
This "Legend of Charlie," if you ask me, was nothing more than a PR stunt so the bar's owner could bring in more business. Many people will flock to supposedly haunted places just for a chance to see something above normal. The bar owner got his wish from the looks of the ending of the "Beer, Wine and Spirits" episode I am referring to.
