Pretty sure there are usually for places for bus drivers to pee at layover points. I believe the CTA even constructs toilets or deploys portapotties for this purpose, if there is no amenable business or institution (for example, https://www.google.com/maps/@41.924152,-87.8020309,3a,75y,237.17h,74.69t/data=!3m6!1e1!3m4!1smcGzgOx2Y-YjSuvareGqzw!2e0!7i16384!8i8192 https://www.google.com/maps/@41.924152,-87.8020309,3a,75y,23... sure looks like a toilet). Now, it's possible that COVID has affected some of these agreements (e.g. if the institution is a museum or something that is temporarily closed) and of course some of the bus routes are long and sometimes drivers must have to go in the middle.
