30 years ago I was a dealer and part-time floor person. One Halloween night a spooking team came in to the joint and to my pit. The BP was dressed as a pirate, and I swear to you, the spook was dressed, you guessed it as a spook. I couldn't help but laugh. I got directly into the eye line of the spook, and when he made eye contact with me I just shook my head "no". He turned around and walked out, the BP played maybe 5 minutes and then left.
Now I'm sure a bunch of people will jump in here and tell you that spooking is illegal. That is an opinion as far as I know, not a fact. I don't believe there has ever been a spooking case conviction or even a trial that I am aware of. Bob Nersesian is the guest this week on Gambling With an Edge, and if we get time I will ask him about this.
