Hi guys, so I'm in Vegas right now, specifically the Cosmopolitan. I was playing very little in the high limit slots and then jumping around from $5 slots for about a hour. Then the weirdest thing happend as I'm playing the Cosmo slot host approaches and greets me by name. She the proceedes to introduce herself, hands me her business card and tells me next time I want to come into town please contact her and she will take care of me. So my question is, how the hell did she know what machine I was playing at? Do they track players while they are playing? I mean to know the machine I'm playing at and know my name? Kind of weird. Does that mean I was playing up to their standards? Thanks guys any info would be greatly appreciated.
