what will you do if you want to pee but there's no toilet around ?

就拉屎

pee on the street of course no people there.

Well, then find one.
If I was in the wild with nobody's around and didn't know where can find a house, I would choose a thicket that can hide myself.
If on a car and has a long distance to next spot that have toilet, I would find an empty bottle.

I will wait until seeing a toilet

這個嘛。

基本上有時候會遇到這種事情，不過可以的話事情忙完後立刻就去找了。(職業病)
