A polygraph guy badmouths a competitor to a caller; the caller instead hires the other polygraph examiner!

 A potential polygraph client telephoned a Los Angeles -area examiner for a price quote.

Examiner said "I charge $550. There's another guy you'll find that charges less. But I'm better. If you use him, you'll get a fake polygraph test".

As it turned out, Client was a businessperson herself, and saw the lack of professionalism in phone-guy's sales pitch.

She located the other examiner, got a test that day, and was very happy with the results.

She said: "I was ready to hire the first guy, He should have kept his mouth shut".
