Did the boss seem like this was a big deal to them?

Is it possible that there’s a chronic complainer that constantly runs to the boss? He might just be saying something about it because it’s the only way to shut them up, and he really doesn’t care that much.

It just seems like such a silly thing to reprimand somebody for. Unless someone was trying to find you for work reasons and you were off somewhere chatting, then I might understand, but I do see that you said that wasn’t the case.
