I feel as if I'm traveling in a toilet.

I'm traveling from Kimberly to Johannesburg as I type this.First, the bus was 50 minutes late but we were not notified about the delay. Secondly, I still have about 5 and a half hours to go before we get to Johannesburg, the entire bus smell like a toilet, I the smell is so strong I cannot even drink water nor will I be able to use the toilet for the duration of the trip as I cannot even begin to imagine what is going on in there.

This is my worst travel experience
