I didn't expect this to be an actual description of a security event, but just a rhetorical observation: of course Panera Bread doesn't take security seriously. There's no "security" in the name of their company. They are not in the security business. I think they do actually take bread seriously. And store location, and customer service, and stuff like that, because that's the kind of business they are.
Because of PCI you can expect they probably do handle your credit card (except apparently the last 4) reasonably well. Because of other regulations you can expect they take food safety seriously. They take basic business operations seriously because there's a bunch of professional business-runners, and they know they really have to.
