After Chipotle closed all of its restaurants during lunch on February 8, the chain offered customers a free burrito to make up for it.

People who texted "Raincheck" to Chipotle's designated phone number received a coupon to be cashed in anytime before February 24. But if you're among those still holding onto burrito code, do yourself a favor and don't tweet a celebratory picture of it. If you do, somebody will steal it and make off with your lunch.

That's what happened to Enzo Martinez, New York Magazine reports. Martinez posted a picture of his Chipotle coupon on Twitter, where @ayoo_eliii spotted the it and used the freebie for himself.

"Thanks for the free burrito dumb---," @ayoo_eliii tweeted with a picture of his stolen rice and bean-filled prize.

Martinez is out a free burrito, but he's not the only person having a rough time with Chipotle's latest promotion. Maryland attorney Hank Levine's cell phone number is so similar to Chipotle's that he spent an entire day fielding text messages from people asking him for free burritos.

Moral of the story? When it comes to free burritos — never tweet.
