An attendant exits a "Pit Stop" public toilet on Sixth Street, Thursday, Aug. 1, 2019, in San Francisco. A 5-year-old portable toilet program in San Francisco that provides homeless people with a private place to go has expanded to 25 locations in the city and has spread to Los Angeles. Not everyone who uses the “Pit Stop” toilets is homeless, but advocates say steam cleaning requests have dropped in surrounding areas. (AP Photo/Eric Risberg)
