well he got fined, lost some points, Im sure the other riders told him what they thought of him doing it. hopefully he apologised to Rondel later. they were never going to dock him time. and it was a bit blink and you missed it, just happened to be caught on camera.
there was some unfriendly pushing and shoving post finish stage 1 I saw with a couple of riders who werent happy about something one of them did in the finish sprint but it didnt get picked up from what I can tell so nothing happened when they could easily have been given the same kind of fine.
