It shall be unlawful for any person to operate a mobile service unit for the dispensing
of gasoline or similar flammable liquids at retail, for delivery directly to the fuel
tanks of motor vehicles, within the city, including but not limited to the retail
sale of gasoline from service trucks or mobile units for delivery to motor vehicles
on private or public parking lots. This shall not be interpreted, however, to prevent
operators of regular service stations from delivering small quantities of gasoline
or similar flammable liquids for emergency service, such as to the vehicle of a customer
whose automobile has run out of gasoline completely and cannot be operated.
