Has a date where some chick brought her friend ever resulted in a good date?

Sounds like setting yourself up to create conflict in a relationship that doesn't even exist yet.

There's no other way to read this besides "I think you are a horrible person so I need protection on our public date, why am I going on a date with a horrible person? I wanted dinner"

That's how it reads every single time, and men are expected to be cool with it, or they are proven to be horrible like previously assumed.

It doesn't matter if they made themseves afraid of men or not. It's a set of ideals rooted in misandry, and it doesn't help women or men.

Is she hot? Because if I'm paying for the friend, too, then I'm expecting a threesome at the end.

Being this weird about not paying would be an instant no for me. Around here it's the norm that everyone pays for themselves on a date and even implying that someone will want you to pay for them is pretty rude. The only non-rude way to pay for the entire date is to ask for the full check when the waiter comes before the other person can ask to split it. Usually with the line "I'll take this one, next one's on you ;)" which doesn't really mean that the next one's on them but is more about the implication that there will be a next date.

It looks like I’m going on a double date.

It's a test and you failed it by being weird and strange and obnoxious, just let her bring her friend it's literally not a downside for you. She'll feel more comfortable by bringing her friend which can only be a good thing for you.

I don't really consider myself to be particularly spectacular in the social department but even I wouldn't have reacted like that. To be crass, why wouldn't you want more girls on your date?
