The point is, it is useful information for surveying.
eg if I see a shop missing an opening hours tag, I would want to visit 
it, to check what the hours are. But if they are not displayed anywhere, 
then that survey trip is a waste of my time and effort.
If I know the hours are not signed, it means I would have to use other 
methods, eg ask the staff, or phone them up, or check their website etc. 
Or sit there all day, and watch what time it actually opens...
