And remember, the cashier also has the ability to waive duties.

So if you find yourself in a packed customs hall and the only think you have to declare is that you've busted your allowance, use the kiosk, get the receipt with the $ symbol and try your luck with the cashier. At the very worst, you saved yourself a whole lot of waiting in line.
