J'adore when the subway doors let out their "doors are closing" alert signal and a couple of lucky latecomers rush through, just in time to miss the final clenching. If the victorious latecomer is foreign, they will sit and grin in amazement at their skills for the next couple of stops. If they are Parisian they will continue looking pissed off as if to say, "Putain! How dare the metro doors close before I'm ready to board!"
On the other hand, I also love watching people miss the subway completely. In that case, the victory is all mine!!!
