Pablo was updated with new algorithms, there’s more randomness to the process when I went through CDG a couple of weeks ago. I think this is their way of spot checking folks with purchased goods to make sure they have them on them like they’re supposed to. I got red marks on small items like purchases less than €400. The system wouldn’t be as effective if everyone got through automatically would it?
A Chanel SA at Rue Cambon, today told me about the more randomness feature of Pablo, it seems to be a known update.
