Thanks for confirmation!

Unfortunately, if we don't know the opening_hours=*, we cannot add them. 

If they are not signed on the ground, and website is not provided, only way to know them would be to enter the store and ask the owner, and then leave a Note.

If you (or someone else) does find the opening hours, please leave a new Note with them or reopen this one. 

I'll close this Note as unactionable then. #notenoughinfo
