I suggest that if you do pick up a players card left at a slot machine you pick one left at a penny or nickel slot.
A while back in Vegas, I picked up someone's card and sat down at a blackjack game. Playing perhaps 40 minutes or so, a guy with a name tag that said he was an executive host came up to me and asked me if I had just sat down. He then said that they must have the wrong card in as he was Mr X's host, Mr X only played machines and I was not Mr X. Told him I had been playing a machine earlier and must have taken the wrong card out and then he offered to get me a new card. A quick never mind, I had to go now and out the door, coming back on a different shift to cash out. Figure, most penny slot players might not have a host who wants to come by and say hi.
