Sometime ago in Vegas while playing blackjack, drinking, and acting somewhat drunk, I was befriended by a stranger at my table. This guy claimed to be from out of town as I was and seemed to be more than a little concerned about my welfare. I'm not especially outgoing, particularly when playing, so this really made me wonder if the guy was a casino employee sent to watch out for me. I've used this drinking cover a lot of times and never has anyone been concerned about my drinking. Have any of you ever heard or experienced a casino employee watching out for a drunk?
