Toilet Bowls

Every time I see a toilet bowl having its lid closed, I fret. Opening it can have only 2 consequences. One, you are relieved to see a relatively clean toilet bowl for you to either stand peeing or sit shitting. Two, the contents in the toilet bowl send you have nausea for the whole day and nightmare during the night.

I have had 4 times here to have to face this situation. Out of these 4 times, I have had 3 of the second consequence I mentioned above. Why can't the previous user do a simple thing just to pull the flush? It doesn't take a lot of energy or effort. It takes less effort than trying to clean your ass! 

So what is wrong with these people?!?!
