Road rage
Just because you haven’t personally wronged someone doesn’t mean they won’t take their anger out on you. It’s a sad fact of life. If a company does you wrong, you, as a representative of that company, are forced to face the consequences. We’re not saying it’s right. We’re just noting that it happens.
This guy was driving down a road when a madman comes zooming past him, cuts him off, then brake checks him. The mailman pulled over on the shoulder and found that the mad driver had done the same. He got out of his vehicle, went straight up to the mailman, and berated him because he had to pay to send a package. Some people are just weird.
