Change Girls Pen did not work on my $100 bill and she very discreetly pushed a button to summon security and within seconds there were 2 thick neck gorillas in plain clothes that came out of nowhere!
Like stink on poop and standing behind me. When the pen worked to validate the Bill, they dissappered just as fast! I still never got to see where they came from. I find it odd these robbers are able to leave the casino with out incident. Maybe thats what the casino wants....no incident there!
