Should I care why your restaurant is closed today?

I walked past a restaurant on La Brea which gets quite a bit of foot traffic and spotted this sign in the window:

If a restaurant is closed for the day then the end result for me is the same: I can’t eat there that day. The reason doesn’t really have an effect on that status. So why go into detail about the reason for the day’s closing? Do you suppose it has more to do with not wanting passers-by to think that they’ve closed for the day for no good reason, or because they wanted passers-by to know that their food is good enough for a billion dollar movie studio?

You tell me in the comments.
