In a practical today, it turned out that our task deviated from what we were supposed to do in the manual, I got shouted at by my attending lecturer,

"Jesus Christ, I don't know where your from but this is just stupid"

1. I'm not foreign, but the lecturer is
2. Because we deviated, our answers (in my opinion) are incorrect
3. Also general rudeness

I was shocked by this, but then again I'm not really bothered because it's not racist for me

Thoughts? And harshest thing lecturer said to you?
