This is bizarre. I seem to have lost my French bank card. Used it this morning at the pharmacy and haven't thought about it since, but I just checked there and they haven't got it.
So…did I drop it?
Seems unlikely, but the state I was in this morning, anything is possible.
Anyway, it's cancelled now. Just need to go and ask for a new one…tomorrow morning, because the central CS office is absolutely useless for anything but cancelling it.
