I'm not questioning your observation, but why do you think people stopped going out to eat 4-8 weeks ago? Two months ago things seemed rather rosy. Did all of those people staying home to eat know something (or experience something) that the rest of us didn't? I mean, they weren't all working for packaging companies, etc.
We have not seen a slowdown in work, including deals, acquisitions, product development, etc. If anything it's been the opposite. Now, we may start seeing things slow a bit given what is going on. Of course some of that will be overly reactionary, possibly resulting in a self-fulfilling prophecy (at least in part).
