Starbucks’ decision to restrict its restrooms to paying customers has flushed out a wider problem: a patchwork of restroom policies that has left Americans confused and divided over who gets to use the loo and when.
Rules about restroom access in restaurants vary by state, city and county. New York requires restroom access for customers at food establishments with 20 or more seats. California requires larger restaurants to provide restrooms for customers and guests, but only if they were built after 1984. In Chicago, restaurants don’t need to have restrooms for customers unless they serve liquor.
