How do you put up with it?

Yup, aircraft-after-pax-disembarked often bear an uncanny resemblance to my kids' rooms.
And some people are indeed swine.
But I believe the garbage explosion is mostly due to the fact that many people really do not know where to put their rubbish. Those sick bags we provide are rather small, and most of the bins are well hidden.
I'd even go as far as saying that if all the pax did throw away their own rubbish during flight, the waste bins would be overflowing in no time.

So in some ways I'm grateful that they don't; trying to find enough space for the waste we collect is hard enough on most aircraft, regrettably.

Wombat, personally I am far more offended by the rubbish management throws at me than by anything the pax ever do!
