When i stayed in Las vegas in the late 90s at the Mirage Hotel i must say i never noticed any security except the huge chap who stood by the lifts and released the velvet rope so you could get by and into the lift and up to ya room,,,,,
As i had no interest in gambling i spent most of the time speaking to prostitutes at the bar and they enlightened me to how much they earn plus the amount of peeps they had to pay backsheesh/bribes to so they could work,,most seem to be doing this so they could pay there uni fees,,,,,,s2
They probably found your accent charming.
