But their unique way of slicing bagels isn't St. Louis' only questionable practice.
On Monday, Twitter user Alek Krautmann shared a photo of two boxes of bagels from Panera.
But not if you live in St. Louis, apparently.
However, Senate Minority Leader Chuck Schumer of NY wasn't buying it over the traditional horizontal slice.
"Thank you for reporting this crime, but we only serve New York City, where this would NEVER happen", tweeted NYPD Chief of Detectives Dermot F. Shea.
Rubin also points out that unlike, say, New York, St. Louis doesn't have a plethora of bagel options.
"Nothing reminds me more of the summer than a st louis style hot dog", Trey Smith, a social media editor at Vice, tweeted.
How do you slice your bagels?
The only people who didn't seem to understand what the fuss was about was the Panera bread chain, who had sliced the bagels for Krautmann.
A photo of a St. Louis-style sliced bagel prompted outrage and debates across the internet.
And some also started destroying other foods and calling them "St Louis style".
