> "It was near the end of the working day, around 5pm, as the person coordinating the developer recruitment in our area I ping’ed our Slack channel to encourage our developers to start reviewing some code tests from job candidates. One person replied: “My end of day activity is doing the stuff I should have been doing all day instead of the other things that came up.”"

The developer is being treated poorly and gave a response to indicate why s/he was being treated poorly. I don't see the problem other than the person coordinating developer recruitment should respect people's time more.

> "A senior software architect who I used to respect walked close by in a meetup. We worked for the same company a while back so I smiled, said hi and was about to start a conversation, he quickly cut me off with “I need to get a drink” without looking at me and wondered off."

If I knew the person well enough, that one is actually a "I need to talk away from here" or a warning to not talk here. I've had friends go with that, but it really is not clear from the context what is going on or has gone on.
