I come to Las Vegas once a month, I stay at Caesars Palace or Bellagio. Right after the casinos reopened in 2020, security was very prominent, particularly admonishing gamblers whose mask didn't cover their mouth and nose, a month later they were gone; but one would see security "here and there". Now it is difficult to find any security agents. Pre-Covid, Bellagio in particular, had security "all over the place"...not now.
In Atlantic City Casinos the security force is very conspicuous.
Labor shortage in LAS.
