A controversial public toilet with a$1.7-million price tag has been delivered to its resting place in San Francisco. After multiple setbacks and public outcry about the cost of the single-stall modular facility, it was offloaded yesterday in Noe Valley. It will be installed soon. After coming under fire for the cost, city officials changed their minds about purchasing the toilet. But two outside vendors offered to cover the expense, and now it is being installed at no cost to the city. Now the question is, how long until it gets stolen?
