It's good to help people out at work.
James is working away at his desk when Bill, his colleague comes over to ask for help him with a file.
James wants to respond to Bill's request for help.
James tells Bill that he'll be over to help as soon as he just finishes up what he's working on.
James tells Bill he doesn't have time as he's working on something and for him to ask someone else.
Bill is happy James will take the time to help him sort out the file and is appreciative.
Bill is miffed that James has blown him off and stressed that he has to look for help elsewhere.
