Be like the wise old bird: the more he knew, the less he spoke.
Don't tell the world your vacation plans, dates, etc. before you go.
Close family and friends you might, but the grocery store clerk, no.
A lady in our town was chatting with the grocery checker.
"I only have to cook for myself this week, my husband will be away at a meeting."
All the while writing her check for the groceries.
A man broke in her house...bad things happened.
They caught the guy.
He was behind her in the check-out line, heard the conversation, and eyeballed her address on the check.
Resist the temptation to celebrate loudly/brag when you hit a good hand/jackpot.
When someone sits down next to me at a machine and asks "how are you doing", I just say "oh, up and down". (Of course "down" is often the truth!)
Lurkers are...well, we can't know where they are.
Don't stand at the cash machine counting your bills. Stick them in your purse/wallet, walk away, sit down at a machine and discreetly count them, hang around the casino a few minutes.
Hopefully a lurker will move on to a 'mark' not surrounded by people.
I put my machine service light on and stop playing if someone pesters me.
They'll leave, usually, and are mostly harmless, but you never know.
