Well, years ago when I was married, my wife & I often went to Las Vegas.
We were out until 3am & we went right to sleep when we got back to our hotel. I put the "Do Not Disturb" sign on the outside of the door.
Around 4am, I hear the door rattling. Then the door opens (no chain back then) & a woman starts walking in - with 3 guys behind her.
My wife woke up & screamed. I rolled off the bed, grabbed my gun from under the bed & rested it on the bed, pointed at the door. The woman yelled, "He's got a f-----g gun!" & all 4 started running down the hall. I called the front desk & they had hotel security grab all 4 of them. Great job, Circus Circus!!!
Later, Las Vegas police told me the woman was a hotel housekeeper & she made extra money letting in burglars with her room keys.
Who knows what else the 3 guys had in mind........
