What is the main characteristic of service stations located inside buildings?

The primary characteristic of service stations located inside buildings is their design to dispense fuel into motor vehicles. These stations often cater to urban environments where space is limited, allowing them to serve customers who need fuel without requiring a traditional outdoor station layout.

Such stations are engineered to accommodate fuel dispensers, thus providing the same essential service as conventional gas stations while integrating into the building's structure. This approach enables easier access for customers, especially in busy city areas where convenience is vital.

While some service stations might focus solely on food and beverages or lack fuel storage tanks, that does not define most service stations inside buildings; their crucial purpose remains the ability to dispense fuel. Additionally, while certain areas may have regulations affecting fuel dispensing capabilities, generally, service stations inside buildings are equipped to handle this function.
