Perhaps its just me, but I've had a few experiences with hosts that left me unclear; are you my host? (Apologies for the lengthy context for the questions) A a California local, a host sought me out during a long session, max bet, handed me her card, told me to call for anything. I knew I had a host. I stopped in the Cosmopolitan host office last Fall, and a very friendly host-on-duty answered some questions, reviewed my history, gave some advice. Handed me her card, told me to call if I ever needed anything. Am I obtuse? Was that an indication that she was my host? I thought she was just being polite. Next trip to Cosmopolitan, I stopped in host office, reviewed my play with host-on-duty, made mention of advice from prior trip. Asked if I was "host-worthy" , was told yes, had my spend back-end comped, and got her card. Same exact comment "call me if you need anything." Glad it was clear that I had a host, it still left me a bit confused. I left Aria yesterday. Day two of my trip,, I wandered into host office, to ask about an invitation slot tournament, and "is my play on track to earn me a host?" A host handed me her card, told to check back for codes to the slot tournament. The host saw me on floor next day, confirmed I got her message about the slot tournament. I asked if she could help get me late checkout. She called me later to confirm late checkout. I stopped by host office morning of checkout, she was working in a different location. I didn't play as much as intended, I really only wanted to ask if I'd done enough to catch a host's attention. Host-on-duty called her. Quick call, hung up, "she said to tell you she's taken care of your bill." That surprised me. My bill, after f&b on an offer, was near $500. I followed up by email later, thanked her, and the reply was: You are very welcome. I am happy to help. I hope you enjoyed your birthday weekend. We hope to see you here again soon. And, once again, I don't know if I have a host. So, with that too-long explanation, my question is: in the absence of a host approaching a player, or at least saying "I'd like to be your host," how does a player know if hosted, or if a host simply took care of something?
