Well here are some more reasons I have never taken the tip very serious.
This sounds a little less than regular customers........
"The steak house was filled with the bar crowd, employees have told police since the investigators learned of the possible sighting a week ago.
The waitress said that Levitt and Streeter had been there before, but not at least for a couple months. Customers and at least one other employee agreed." NL June 24,1992
This sounds like they were covering the same ground we are right now.
"We have had sightings (at an Apco station and George's Steak house), It is absolutely critical to the investigation that we validate these sightings, and that is difficult to do. You don't have cash reciepts, a credit card that shows some convenient time and place. In that sense there is a questioning. We look at the credibility-- not that people are giving us bogus information, but we must establish credibility, so that information means something to us." Police Chief Terry Knowles NL June 26, 1992
This sounds to me like the waitress and the sighting and possible date might be in error.
"Springfield Police say a man who was thought to have talked to three women at a restaurant early on the morning they disappeared was not there that morning and does not know the women" NL July 1, 1992
