Hi impiaaa,

Thanks for the feedback. I've added the covered=yes tag as per OSM-wiki tagging guidelines provided on the following OSM Wiki page: https://wiki.openstreetmap.org/wiki/Tag:covered=yes
As the drive-through passes under a roof with a wall on one side and the building is at ground level, I added the covered=yes tag to the access road and removed the layer=1 tag from the building. 
Please let me know if you think otherwise.
