That's not how chat works - you're using a wrong analogy, and probably causing confusion and frustration amongst your coworkers. Chat is nothing like walking up to someone. "got a sec" is a waste of time and an annoyance, the sooner you learn that the better. Just put the greeting with the question: "Got a sec, I was wondering if blahblahblah?" Or even better "Hey, I was wondering if blahblahblah". Then they can respond right away, or not, or say, "Give me a few and I'll get back to you". This is how modern chat works, please learn it!
