Yes, I agree that usually there's a workaround to the PIN; we almost never had trouble....but, when we did, even if it was user error on the cashier's end, it didn't really help fix the situation and we needed to have an alternative. It was super super rare to have an issue when there was a person processing the payment though - the times we struggled were automated kiosks, like buying train tickets. The press enter to move past PIN didn't work on those.
