This happened only a couple of hours ago. I'm a new waitress, and I started my third shift at my workplace (a bar/restaurant.) I should also note that I'm not very experienced and still training. There was a total of 7 waiting staff and 1 restaurant manager (Becky) working this evening. 

The Boss came in today, and gathered the restaurant staff together. He said there's too many working and a couple of people should go home. One girl (call her Emma) offered immediately, so The Boss let her leave. He then asked the remaining 6 people who else wanted to leave.

After about 10-20 seconds of no one offering, I offered as I had a long shift the next day anyway and I'm not as qualified (there were a couple of large bookings so they needed the most qualified staff.) The Boss said okay.

Another girl (lets call her Kathy) said quietly and sounded pissed off, "I've been in since for 6 hours, and I've got the same shift tomorrow." I then offered that Kathy should go home.

The Boss agreed, but Becky said she needs qualified staff and I'm not fully trained yet. Kathy then said Emma was her ride home, on top of working those long shifts. I'm stuck in the middle of the three, feeling very awkward considering I'm brand new and not wanting to rock the boat or bother/upset brand new co-workers.

Eventually Becky told me to go home, leaving Kathy to say "fine", refused to look at me, Becky, or The Boss, and walked off. I asked about my shift tomorrow and the manager seemed somewhat short with me. I left quickly after that.

Is someone in the wrong here? I'm pretty damn socially awkward, so is there any advice on how to handle this situation? Specifically, any advice in case Kathy or the manager is upset towards me and acts passive aggressive/straight up aggressive?
