Jessie is only trying to help here, and for that she gets figuratively slapped in the face...
She turned back to look at me. “Yes, and you're Jessie,” she said.
It didn't sound friendly or welcoming. She actually gave the impression of being quite cold and distant.
“I mean no offence, Jessie, but I'm actually trying to look for a book here. I have an essay due and unlike some people, I can't wait for someone to do it for me.”
“What's that supposed to mean?!” I said, losing my temper a little.
