McDonald’s Built Its First Drive Thru Window Because of One Army Rule in Arizona

The Egg McMuffin has been handed through a McDonald's window to sleepy American drivers since the Ford administration.

Few of those drivers know that window traces back to a dusty Army town in Arizona.

The soldiers stationed there could not walk inside, and a local franchise owner found a way around it.

The Uniform Regulation Behind the Sliding Window

The town was Sierra Vista, right outside the gates of Fort Huachuca.

Soldiers from the base were required to stay in their vehicles when wearing fatigues off post, according to McDonald's corporate history.

That meant a lot of hungry troops who could see the Golden Arches but could not set foot inside.

Sales at the Fry Boulevard restaurant suffered.

So licensee David Rich did what American business owners do best – he fixed the problem himself.

His fix was a sliding window, so troops could order without ever leaving their cars.

McDonald's first drive-thru opened on January 24, 1975, complete with a menu board and a Ronald McDonald statue fitted with a speaker and microphone, KGUN 9 reported.

The post commander and his daughter were first in line.

As of 2023, that same Sierra Vista restaurant was moving roughly 1,000 vehicles a day, with the drive-thru bringing in about 80% of its business, according to the station.

The original window sits in the Henry F. Hauser Museum in Sierra Vista, and the Ronald statue still stands at the current restaurant.

That one workaround grew into roughly 70% of McDonald's business in the United States, according to the company.

McDonald's Was Late to the Breakfast Party

The drive-thru itself was not a McDonald's invention.

Red's Giant Hamburg in Springfield, Missouri, often gets credit for the concept in 1947, and In-N-Out rolled out a two-way intercom in California a year later, Fox News Digital reported.

Breakfast was not a McDonald's first either.

Jack in the Box beat McDonald's with the Breakfast Jack – egg, cheese, and ham – back in 1969.

McDonald's breakfast came from a franchisee, not a boardroom.

In 1971, Santa Barbara owner Herb Peterson set out to make a fast-food version of eggs Benedict.

Packaged hollandaise sauce flopped, so he swapped in a slice of cheese and Canadian bacon, according to McDonald's.

He rigged up Teflon rings that turned fresh-cracked eggs into neat rounds that fit an English muffin.

In Ray Kroc's telling, Peterson would not say what the sandwich was until Kroc tasted it, Time recounted.

The Egg McMuffin hit test markets in 1972 for 63 cents.

The name came from Patty Turner, the wife of a McDonald's executive, and Kroc credited it with helping the sandwich take off.

The national rollout wrapped up in 1975 – the same year that sliding window opened in Arizona.

Capri Cafaro, creator and host of America the Bountiful, told Fox News Digital that McDonald's "were later adopters to some of these trends that are so embedded in our fast-food culture today."

She credits "convenience and an 'on-the-go' lifestyle" for the takeover.

Interstates, new suburbs, and a car in every driveway did the rest.

Starbucks opened its first drive-thru in 1994, and by 2022 two-thirds of its sales came through the window, according to Business Insider figures cited by Fox News Digital.

One Franchise Owner Outsmarted Every Corporate Planner in America

The best ideas in American business rarely come from consultants.

They come from a guy in Arizona watching soldiers drive past his restaurant and a guy in California who could not get the hollandaise right.

Neither one waited for permission from a committee.

David Rich did not commission a study on customer behavior.

He put in a window.

Herb Peterson did not hire a focus group.

He invented a kitchen tool.

That is the free market at its best – a local owner with skin in the game solving a real problem for real customers.

And it started with the United States Army.

The soldiers stationed at Fort Huachuca never asked for a revolution.

They just wanted a burger without breaking uniform regulations.

Half a century later, every mom juggling a minivan full of kids and every trucker grabbing a sausage biscuit at dawn owes those soldiers a thank-you.
