I've seen the same blackjack thing going on for years. You described it exactly. I asked several times what they are looking for but never get anything but a blank stare as if to say "I don't speak English" or "It's a secret". When Harrahs Rincon stopped bussing in the seedier element of that particular group, the blackjack seekers stopped altogether. When visiting other so cal casinos I often see the same faces still doing the bJ "dance". Never could understand why sit down to play one hand, usually one quarter, then collect the ticket and continue on. The dance lasted from the time the bus arrived until the time the bus left. Seven days a week. Same faces.
