This is why I can't work in an office. The last one I worked in, people kept waking up to chat "for a sec", when it took at least 10 minutes regardless of the inquiry.
Just as I'm starting to get myself back into my workflow.... "Hey, you got a sec?"
Sure, looks like I'm not going to get anything fucking done today, so why the fuck not. The only people I'm disappointing is the employer. I can have a chat. It's fine. Not like this will negatively affect my ongoing employment.
