Have you ever spent any time outside in the actual existence that most people find themselves inhabitants of, or do you live entirely within the realm of rhetoric? I've seen businesses allow non-employees to use private bathrooms and society didn't crumble as you seem to believe would happen. You can argue your points but frankly that's all irrelevant, the first question here isn't one of procedure, bureaucracy, and protocol; the question is one of human decency. They lack it, that's the problem. They could have let him use the employee bathroom just fine but they wouldn't have even needed to do that...

They didn't have one. What, are they supposed to build a public restroom for him?

If you read the article you'd see they do in fact have facilities that are easily available to the public but they've closed them because they don't want to go through the work of maintaining them. That's another reason I can tell you don't actually exist in the real world with the rest of us, gas stations all have public bathrooms. How do you not know that?

Regardless, if this company has the resources to process, maintain, transport, and dispense uncountable gallons of highly combustible fuel then they can certainly handle a steady trickle of human tinkle. Every other gas station in the world does. If they are not willing to provide the services that are expected of a gas station than their potential customers should be well aware and they should consider that fact when they decide where to spend their money. Facebook, news websites, and reddit are all good and decent platforms to use to inform consumers on how to spend their money wisely so I really don't see just what in the fuck you are bitching about.
