An anti-ketchup vendor, famously known for being Tiger's singing hot dog vendor, was reportedly fired from his job due to his condiment beliefs, Inquisitr reported Thursday.

According to Deadspin, Charley Marcuse, the hot dog vendor who gained a reputation at Comerica Park for singing while offering patrons hot dogs, was fired last week by the Detroit Tiger's concession company. That time however, everyone thought that the singing vendor got fired for another not-so-serious offense: his singing.

However, Detroit News pointed out that after its own investigation on the issue, it found out that Marcuse was fired not because of his singing but due to his strong opinions on what should go and not go on a hot dog.

"There are rumblings the real reason was ketchup - or Marcuse's disdain for it," the newspaper wrote. "Marcuse, at the ballpark and on Twitter, has been a strong crusader for only putting mustard on a frank. And some fans thought he got combative when they asked for ketchup. There were complaints filed."

Meanwhile, the concession company, Sportservice, has not issued a statement commenting on Marcuse's firing as of late.

Detroit News also stated, "Asked whether condiments actually were behind his dismissal, Marcuse was vague. 'It was general employee conduct,' he said, relaying the reason he was given."

Charley Marcuse had been singing for all of his 15 years of being employed to selling hot dogs, so many questioned why he was dismissed for such vague reason.

"Only barbarians enjoy ketchup on hot dogs, so Marcuse is certainly to be admired for being Against Ketchup. But he was working in the customer service business, after all, and the customer is always right-even a customer so coarse as to demand ketchup on a hot dog," Deadspin wrote.

As of late, the anti-ketchup vendor has filed a grievance, but it is yet to be scheduled.
