A Dublin-based café has been heavily criticised for its controversial comments on customers ordering gluten-free food.

In a Facebook post, The White Moose Café said that guests who ordered gluten-free food would be required to produce a doctor’s note.

“This morning a girl asked us if we did gluten-free pancakes and when we asked her if she was a coeliac, she didn’t even know what the word meant and then proceeded to order regular, gluten-rich pancakes anyway,” the post said.

“From now on, guests who demand gluten-free food are required to produce a doctor’s note which states that you suffer from coeliac disease. Guests following a gluten-free fad, who don’t even know what gluten is, can cop the f--k on and eat regular food like everybody else.”

Owner Paul Stenson defended the comments as just "a bit of fun" and believes people are taking the page too seriously.

"While you can never really underestimate the stupidity of the general public, the reaction on the page has taken their stupidity to a whole new level," he said.

"If they took the time to read down the page they would quickly realise that all of my posts are a bit of fun. It's funny how they think I'm serious about a doctor's note but they don't seem to mind me giving Valium to screaming babies."
