I am usually very carefull with machine tickets I treat them like cash. Put them in my wallet as soon as I stop playing as soon as they come out of the machine. I lost one at Terribles, not exactly sure when. I had trouble with my players cards since the Monday I arrived. It was not working in the kiosh machine for promotions. So I was going constantly to the players club, as they were telling me it should work now! My concern about the promotions cost me about $200. The odds of me getting more $100 in promos very slim. I also learned to report a loss of ticket to the slot manager as soon as possible. Hope this helps someone!
Keep your priorities in order.
