Pooing in Foreign Lands

I just recently came back from a trip to Lebanon. Like many other Middle Eastern and Asian countries they ask you not to flush any paper down the toilet. But it is just habit to wipe and drop. I mean, those of us who have grown up in the West have been doing it since time immemorial - literally. Can you remember a time in your life when you were not potty trained and wiping yourself?

Anyway, in those places that beg of you not to wipe and drop but rather to wipe and then throw in the waste basket, why is it that they put the sign up behind the toilet? Unless that sign is staring me in the face as I am doing the deed, I am not going to be able to break the habit. Heck, even when (after many mistaken wipe and drops) I decided to physically remove the sign myself and place it on the garbage can and place the can right in front of the other can so that I am basically straddling it as I poo, I still can't manage to break the habit of wiping and dropping in order to wipe and waste. Usually I get the hang of it on the last day of the journey and then it is time to go home.

Who is the poor soul who has to empty the trash can anyways? Am I, in fact, doing some kind of humanitarian service by maintaining the wipe and drop habit?
