They just know that the people they send these offers to are going to play. Unluckily for them I'm not the type to sit glued at the table and play constantly and I will go home with my winnings, but I will give them some action not just one bet.
But yes if I don't play enough that same host will probably send me a text.
I should get hold of my friend who was living at Encore. After the disaster hit he eventually had to move out and he never even flew home ended up renting a place and staying in Vegas all this time. I would assume that he is back there now, inside Encore, I should get a report on how it is.
