Ah
How to piss off SNCF train managers
Question them when you know the rules better than them 😀
They announced on the PA that Name and Telephone number on the bags is obligatory
When they did the ticket check I asked them about this
One got shirty with me, but when they looked in the SNCF conditions they couldn’t prove telephone has to be on the label
