I'm also surprised when I take a photo of a MACHINE and being told not to do so.
I needed to take a photo of the pay table and analyze it in a comfortable bar stool.
Bid deal!
I'm careful NOT to have my flash enabled. It messes up a screen shot,anyway.
Some casinos don't care. Even at a live game!
It was some 25 years ago at the Strat. Got a photo of myself and my 2 brothers at a BJ table.
My father was granted permission. Back when there was FILM in a camera.
"I don't care,go for it",said the nice dealer.
There are videos posted of a live craps game,until the camera is discovered on You Tube. Great fun!
In the comments,some people will catch a bad pay out! Sure,we see lousy bets being made as well.
Videos are a BIG NO-NO.
