That happened to us in Feb. @ Ballys, playing let it ride, the pit boss came up and said, @ 7 the table goes up to $10. It was s full table, many of us haas been playing several hours. @ 7, the whole table cleared out and most of us went to the $5 3 card tables. Ballys only had 2 let it ride tables. I played 3 card for 2 more hours and never did see anyone sit down at the one table.
Hubby and I were playing @ Aria a few years back at a $10 3 cared table. Pit boss came up and changed it to a $15 but told us we were fine since we'd been playing awhile. About an hour later he comes back and changes is to a $25' told us the same thing. We asked the dealer what that was all about and he said they wanted to shut down that table but would stay open as long as we wanted to play since no one would want to play a $25 game when there were 3 others still at $15.
