The toilets BECOME dirty because people use them. Unless 2B's pax don't use toilets, they'll have clean toilets. What does this have to do with GF? That was a little from left field. Do you have a bone to pick with them? Back off a little, matey.
No bone to pick with GF. I even fly them when I have to.
It just the generaly held view by people that have flown on GF that the interiors of their planes are crap. And yes, their toilets are filthy. Better take of your rose colored glasses.
If is attitudes like yours that have made GF the backwater of ME aviation. Even Saudia's planes are cleaner.
Piece of advise there matey: Stop attacking criticism, listen, learn, and for heaven sake's clean the interiors.
