A vegetarian’s sandwich order at Subway was so sparse that even her own server had to laugh — before she shared it on social media to more mockery.

London woman Anna James, 20, had been drinking when she went to the sub chain — typically known for its meaty, loaded heroes — for the first time last week and ordered only cucumbers, shredded cheese and black olives on toasted bread.

“We were both pretty tipsy and I asked the workers how it worked. I told them I’d never had a sub before and they were really nice. We were just joking for a while before we ordered,” she told Lad Bible.

“I only wanted a cheese and cucumber sandwich which made them laugh and they kept offering me more fillings or sauces. Then I saw the olives so was like, ‘Those too, please.'”

James posted a photo to Twitter of her grinning server taking a snap of her underwhelming order before wrapping it up.

“First time in Subway and the worker took a picture of my order. Am I doing this wrong,” she posted in a now-private tweet under the handle @annajames33.

The server then posted the sandwich to his own Instagram, with the caption “Who orders a subway like this” and two crying-laughing emojis.

Other social media users agreed.

“That’s actually so wrong,” @your_gal_sophie tweeted.

Another Twitter user, @yvngpusII wrote: “I’m hardcore judging you right now.”

“I hope he’s sending that to the FBI,” another user said.

But Subway itself defended her order — and the server — on Twitter, saying: “looks like he’s just documenting a true masterpiece.”
