When you poop on a big public bus where do it go?

If someone were to poop on a big public bus, it would typically remain on the bus unless immediately cleaned up by staff. Buses are not equipped with toilets that can handle human waste like a sewage system. Instead, they may have portable toilets or chemical toilets that can contain waste temporarily. In any case, such an incident would require immediate attention from the bus operators to maintain hygiene and cleanliness.
