Starbucks’ decision to restrict its restrooms to paying customers has flushed out a wider problem: a patchwork of restroom use policies that varies by state and city.

Starbucks opened the can when it said last week it was reversing a 7-year-old policy that invited anyone to hang out in its stores or use the restroom, regardless of whether they bought anything.

Starbucks is ending its open-door policy, which allowed anyone to use its restrooms or hang out without making a purchase.
