Yeah, this trip alone sounds like grounds to be openly hostile.

Exactly. How do you get forced into driving someone? How do you let her sit down at the table if she isn't invited or wanted? How do you let her take food off of your plate without doing something about it after the second, if not the first, time? There's a lot of inconsistencies in this, either that or you and your friends are pushovers.

Force to drive her home. At least that way they're at their place out of your way.

So OP could have a story she could post on FML, of course...

I don't think she had any friends to begin with

She probably doesn't know that though

She probably doesn't *care*.

I am actually inclined to agree on this one. OP allowed her to tag along, nobody forced you into this event.

You raise a very good point actually. I was thinking the same thing.

Some people are very hard to get rid of and don't take a hint or even a direct we don't want you here. This may be the case or op and their friend may just not wanted to say something

Still a YDI. Don't unlock the car door. She's already inside, threaten to call the cops. Go hardcore on the bitch. This was a form of theft, taking their food without consent or splitting the bill. OP and friends could have done plenty to stop this. Even if it was simply shouting at her in unison to GTFO.

I'm guessing op doesn't want to deal with this person's drama or op doesn't want to upset them. I have someone in my group of friends that no one likes but we don't say anything because we don't want to upset her cause all sorts or shit goes down so I'm guessing op is trying to avoid the trouble of them upset. However that person went a little too far and someone should have said something because that is plain rude.

Just go "JOEY DOESN'T SHARE FOOD" on her
