> In the office it was hard to get people to stop turning up at my desk at a time convenient to them, regardless of what I was doing, to interrupt me.

Where I currently work (100% in the office, sadly), there is a coworker who did this to me regularly. He was causing a serious loss of productivity, and wouldn't stop.

So I started doing the same to him, stopping by his cube a few times a day at random to ask some legitimate technical question.

The end of the week I started doing that, he complained to me about my constantly interrupting him. It was causing him to fall behind in his work.

I told him "Of course, I'll start messaging you instead of stopping by. Would you extend the same courtesy to me?"

He stopped needlessly interrupting me.
