@BO29. Well, I could... but I tend to solve my OSM notes myself, so there was no need to do so... Usually I do not have enought time to add the POIs right on the ground so I just create a note. In this case, it is just a transcription of opening hours as they are present at the doors of this POI. Any czech speaker would understand that. If I were adding a note which would need a discussion or in a different country, I would definitely use English! Thanks for your remark!

This POI was added in changeset #142451818 so I am closing this note.
