Does anyone know if Greyhound offers compensation for terrible odor in the bus?

I had an almost 4 hour bus drive today with Greyhound and as soon as you enter the bus, you can smell a very strong odor of bathroom smell. Ofc my seat was all the way in the back and the smell didn’t disappear at all the whole ride😭

Has this ever happened to anyone before and although I can’t physically prove a horrific odor, is it possible to get any kind of compensation?
