Final answer:
Gas/service stations with or without ancillary services provide additional amenities like food services, convenience stores, and car wash facilities, or may just offer fuel without these extra offerings.
Step-by-step explanation:
Gas/service stations with or without ancillary services refer to the additional non-fuel services provided or not provided by the facility. Ancillary services can include a variety of offerings that enhance the customer experience and provide added convenience. These might encompass food services, convenience stores, car wash facilities, auto repair services, and more.
Gas stations with ancillary services are those that offer additional facilities beyond just fuel. This could include an onsite convenience store, a fast-food restaurant, a car wash, or auto mechanic services. Conversely, gas stations without ancillary services provide just the essential services, mainly fuel, without any extra amenities. When answering the provided multiple-choice question, options related to both providing services (like food services and car wash facilities) and those without additional offerings (like stations that don't have convenience stores) are included.
