My suggestion to you would be to do your asking of the 2nd or graveyard shift, since most of the time these are the less tenured people and they also seem to be more lay back types. Also I don't think as many supervisors are around in these types of areas. They are in the pits and cages.

I know until recently I couldn't get blanks from any casino in Louisiana or Miss., but this has changed. Each time I was refused one in the past I always replied slightly loud " I guess you don't want me to provide free advertising for you."
