Unless you're with someone who can watch your food, who places their order at a fast-food restaurant and then goes to the restroom? Weird...:screwy
In any case, as I've said before I don't know if this is racism on display or a coincidence of two different store managers interpreting corporate policy the same way (correctly or incorrectly) or someone (or group) testing Starbuck's corporate policy on non-paying customers using their facilities. One the one hand, I can certainly understand the loitering angle. You don't know if the patron is waiting for others to show up or why, if their intentions are honorable or nefarious. You just don't know. You also don't want people just hanging out at your store causing problems (no matter how minor) for your paying customers. So, I certainly understand the store manager's concerns in both instances. But I also understand the optics as many Black people see it when two men are arrested just for waiting on another of their party to arrive and another is denied access to the bathroom simply because they lingered around too long without placing an order. Some people may see this as a private business operating as it sees fit while others will see it as racial descrimination harking back to the days of "N***ers, stay off the grass, White drinking fountains/restrooms-only". Nonetheless, I still say that while such behavior ("loitering") is to be expected at a coffee house (and that's what Starbuck's is...a coffee house franchise), if it's become a problem at some stores they need to place the appropriate signage at these shops making such visible for all to see. The downside to doing this, of course, is said coffee house franchise risks losing many of its "walk-by" customers who simply want to sit down and read the news before carrying on with their day.
Note: I still contend that the manager at the Philly store was wrong. Once she was made aware that the two men were waiting for another of their party to arrive and especially once that 3rd party arrived and confirmed their story, she should have let the matter go and apologies right there on the spot. She made the wrong choice and now Starbuck's is paying a price to their bottom line and its reputation.
