there are three types of public restrooms:

1) public restrooms within private buildings
2) public restrooms within public buildings
3) public restrooms within public spaces

i thought that i would journey to three separate restrooms, an example of all three types. i thought that each one would appear less or more clean because the first two types are more restrictive, and they are maintained beneath health and sanitation laws. but honestly each restroom appearerd to be about the same in terms of cleanliness.
