She just snapped and went and got two male friends with guns hours later?

Pretty sure that’s called “premeditation”, not “snapping”.

And masks. I don't view this as some asinine tipping situation. I 100% believe this was simply an ugly armed robbery that turned violent when the victim didn't have as much money as the criminals thought. The tip angle seems to me to be mostly media sensationalism and obfuscation by the female perp.
