The Reimu didn't have a badge, so she couldn't have been very well trained. Mind you, she did realise that bringing the Marisa home triggered her master's rage.
That's not how it works, you tell the owner you understood what you did wrong, give a satisfiying explanation about it and wait to see what happens next. You can't go and claim "ok it's over since i apologized!" or anything like that.
Most yukkuri don't even accept what they've done, even if you spell it out for them. Actually, even if the mister did forgive her, I'd expect her to pull something like this again.
