Remarks
To distinguish between gasoline stations of the same brand, located on both sides of a highway, the direction can be added to the streetname of the place. Add behind the street name ri plus a short indication where that side of the highway leads to.
If the gas station also includes a shop, you can choose that as a secondary category. If the shop has different opening times, for instance when at night gas taking is still possible via automatic payment, make an extra Point Place for the shop and categorize it as “Convenience Store”.
