WASHINGTON - Loraine Maurer has been serving customers at McDonald's restaurants in the US for 44 years and at the ripe old age of 94 has no plans to retire.

Since 1973, Maurer has worked at various outlets in her hometown of Evansville, Indiana, and eats from the fast-food burger chain's menu every day. When she's off sick, the food is delivered to her house.

Her favourite dish is the fish sandwich.

“But now I work mornings, and there isn’t anything I don’t like. This morning, I had a blueberry muffin, two fried eggs and a cup of coffee,” she told People magazine recently (March 23), as staff at the outlet where she currently works marked her 44 years of dedicated service.

But it is the customers who keep her coming back for more.

“My customers make my life,” she said, according to People magazine.

“I have travelled with them, gone to ball games with them. They’re friends, not just customers.”

"She's like the sunshine in this place," one happy customer told ABC News. "You come in, she's always smiling, always doing her best."

"She's a sweet, sweet lady," said another. "She makes everybody feel so welcome when they come in"

“After all these years, she remains committed to serving her customers with one of the most delightful smiles around," said Chip and Katie Kenworthy, owners of the restaurant when Maurer currently works.

"Loraine has a loyal following of customers and they look forward to having her take their orders when visiting McDonald’s.”

Maurer - a mother of four, grandmother of six and great-grandmother of seven - works two shifts a week and told ABC News has no plans to retire, although she does think about it when winter comes around.

"I would miss it too much," she said. "I don't want to get depressed and it's not that I don't look forward to going to work... It's not a job.

"I really and truly enjoy it. Life is what you make it. And so I'm trying."
