How does it make sense to suggest that a restroom policy whereby individual patrons are allowed to use their bathrooms absent a purchase is a fundamental change. Firstly, when did they not allow such activity? Just because one store had an incident doesn't mean that an unstated policy wasn't still in effect as a business practice. Secondly, which retailer is play sheriff at the entrance/exit to ensure patrons are not just browsing or loitering? Is it McDonalds. Is it Wendy's, is it Wal-Mart, Target etc. Of course none of these retailers are monitoring such activities. It's the difference between public relations of no consequence to battle a headline of the day from an incident in one location.
