As someone who -- in my workplace -- is more often than not on the receiving end of questions or calls for help, I find it extremely distracting. There have been entire days where I wasn't able to focus on my own work because everyone else had questions to answer, or bugs that they needed help working through. I can't fault them for asking for help, but I definitely get frustrated at the situation, because sometimes at the end of the day I end up feeling like I haven't accomplished anything.
