You have toilet issues? Clean up after yourself.
I do, but I refuse to clean up after others -I do not pay to go on a flight to do so.
Put it down to hundreds of flights, very many in Asia.
Join the club. I flew hundreds of flights in the Indian sub-continent mainly out of Pakistan in the early eighties and also a fair few in Africa. BA CC used to have to explain how to use toilets to people who had never seen a sit down loo before. But that was a cultural issue. Noisy kids being allowed to treat aircraft cabins as their living rooms by holier than thou parents is rudeness and inconsideration for fellow passengers. I don't blame the kids, I blame their parents who want special treatment (first on, bulkhead seats, extra hand baggage, meals first but to name a few) and expect Joe Public to put up with the little darlings.
