This Subway customer found an entire dead rodent in his sandwich

Brace yourself.. There's photographic evidence.

Hold on to your breakfast as you read this story, it’s a gross one.

Jay Armstead and his friend Matt Jones went to a Subway in Lincoln City, Oregon last week and one of them got something quite unexpected in their sandwich.

A dead mouse right there in the spinach.

"It was unfortunate I was the lucky recipient," Armstead told KGW. "It was wet and dead. His tail was curled up and you could see his two front teeth."

Luckily, the rodent was discovered by the Subway employee before it was close to anyone's mouth but still…

Matt posted the photo to Facebook with the caption:

"Look at that beast of a mouse in the spinach at Subway today! Good thing we didn’t bite into it! Amazing! WTF! The manager was in shock."

And while Jay was obviously a little shook too, Matt thought it was only gas.

“It’s the funniest thing I’ve ever seen, but it’s also the most disgusting thing I’ve ever seen. I laughed because I was like, there is no way this just happened,” he said.

The county health department have investigated and found that the rat came from the spinach suppliers and there was no risk to customers' health.

The pair got a full refund.

Which, under the circumstances, is the least you could expect.
