New dealer makes rake mistake... call floor?

[PokerFink]

Venetian last night. 2/5 NL full game. The game is raked, 1 on 10, 1 on 20, 1 on 50 and 1 on 90 (great rake). No flop, no drop.

The dealer is one of the many temporary dealers they hired for the deepstack extravaganza. One player limps in, I make my standard $25 raise, everyone folds. So the pot is $17 (BB + SB + limp + my 5). The dealer pushes me the pot and there are no white chips. I figure she forgot to make change for the SB, so I grab three whites to toss to him when I realize I was pushed only $35 (my own 25 + BB + limp).

I look at the dealer and ask where the other two dollars are. She says right here, points to the drop thingy, and then drops them. I ask her why she dropped, and she says the pot was over 20 and that means $2 drop. I say "no flop, no drop" and she looks at me like I'm speaking gibberish. One of the other players repeats, "no flop no drop" but she still doesn't understand.

(Note that not only did she drop when she shouldn't have, she even miscalculated the pot and dropped too much.)

She is about to be pushed, so she turns to the dealer behind her and asks what is going on. That dealer explains that if there is no flop, she should not take any rake. She nods and stands up to move to the next table.

Do I slow up the game to call the floor over my missing $2? (Not to mention whatever other money she dropped during the half that she shouldn't have?)
