I've never had this issue in US cities. I don't think I've seen an actual _public_ toilet facility, but I've never suffered because of it. Unless you are in a shopping mall it is required by law to have a restroom. Starbucks, McDonalds, Burger King, these all have restrooms and are open to the public. Sometimes they might require a small purchase (like a water bottle). Heck, I was in NYC not too long ago and was surprised to find that all Starbucks have open restrooms (in other cities I've visited sometimes you needed to ask for the key).
