Because we had yet to come against each other, but it is stated in the original ooc that battle is turn by turn. Plus take into account that your character is stealing from right in front of Sera, a Fallen with Inhuman Speed as a power. Sera was right in front of Elisheva on the other side of the bar when the money was tossed down, so it would have landed right in front of here within a foot, maybe two of her. 

To take money, then speak, then drink, then teleport is a slew of actions. Back it up to previously stated point to see if theft is successful or not.
