Terrible Herbst Oil Co.’s well-known mustachioed "Bad Guy" cowboy logos have been fixtures of the Nevada landscape since the company's founding by patriarch Edward R. Herbst.

Herbst started the company in Chicago in 1932 and founded Terrible's in Las Vegas in 1959. Since then, Terrible's convenience stores, car washes, lube shops and gaming facilities have become familiar sights on the Vegas horizon and beyond. The company has grown dramatically over the last 70-plus years, but continues to focus on customer service. The chain has over 850 employees, and product knowledge, quick, efficient service and a friendly smile are trademarks of the stations.

All Terrible Herbst c-store locations sell gasoline, and nearly all sell beer and wine. Stores are open 24 hours a day. The chain's top categories are fuel, beer and tobacco, and the company is working to build up its foodservice offering. Primary competitors are 7-Eleven, Circle K, Rebel Oil and Green Valley Grocery.

Terrible's Car Wash, which it said is the first "green" car wash in Nevada, has been recognized by the Southern Nevada Water Authority for being a water-smart car wash. The company has installed "green" washes in half of its car-wash locations and uses eco-friendly cleaning products and substantially less water per car. Also, the company recycles 40% to 50% of its trash, approximately nine tons per week.
