Well...I guess it depends...how valuable are we talking here?
What if you don't know what exactly it will be but you're pretty convinced that there are something good in there? Cuz.. I don't know, since that kind of thing doesn't really happen in real life... but what if it DOES?
I would need a guarantee before I stuck my hand in something like that lol. And it would have to be something super valuable...like financially secure for at least the next 10 years valuable. xD
Well I guess it makes senae that the narrator keeps questioning the protagonist whether he/she is out of his/her mind, and finally gave in and gone crazy after so many disgusting spitoon searching. After all the game has its own humor, being so crazy in all kinds of stuff. You ever heard of a coffee-cactus? That's a thing in West of Loathing, lol.
