You're a lost cause. The woman broke trust and respect immediately. Presumably they agreed to a date and, assuming you are capable of understanding social situations at all, a date on an app like Tinder is heavily implied to have a romantic purpose between two people unless otherwise specified, which this case it obviously was not. The woman who agreed to a date with the common understanding it would be between the two of them was extremely rude and disrespectful by bringing a third person unannounced. I am not arguing for or against any response by the guy, mind you, but you seem to be incapable of understanding what respect and rudeness actually are

Edit: I didn't initially read all of your comment because the first half was mind numbingly stupid, but figured I should give you a chance to maybe make a decent point at the end. Which you didn't, it just got stupider. If her idea of a date is a guy and her friend, that's perfectly fine and acceptable. She should have said so when they were planning the date. It's on her if she couldn't communicate what she wanted properly and so still, even in your scenario, she is firmly in the wrong
