It's toxic to say your coworker asking for help is a distraction when all people are supposed to be there to collaborate and get things done together.

Imagine someone comes to your desk and says they need help with something and you say "Please go away, you're distracting me" or you simply ignore their presence. How would they feel?

I'm not saying OP is doing it at that level but I think you can see my point.
