If ever you arrive at Marseille airport and plan to seek the toilet at arrival whilst waiting for your suitcase: DO NOT!
There is only one toilet cabinet (one for women, one for men) for all planes arriving. The cueing up of people pressed and urged is almost funny.
Cleanness is ok (but depends on the intensity of the people just before you).
Relieve yourself in flight, not at the airport.
This accounts for flights at the terminal for airlines other than Air France.
