I was playing 2/5 and 5/10 at the Rio and the button was allowed to straddle. When they straddled the dealer asked the SB to act first and the action proceeded from there.
I played at the Venetian, same games, and when the button straddled, the dealer asked the UTG to act first and proceeded from there to the Blinds and then the button. The floor said it was to 'protect' the blinds.
Is this common in other poker rooms? I never saw the straddle (button) skipping blinds...
The games were great in both locations, can't wait to go back!
