Their post, which went up on Facebook and Twitter, reads: "I'm holding an #Ibelieveinsanta rally in O'Connell Street. Please join me and scream 'I believe in Santa' very loudly. I know very little about him and have seen little evidence about his existence, but i still believe in him because.....well....just because.....okay???"

This is not the first time that the cafe has stirred up controversy. Back in January, White Moose hit out at a social media vlogger who asked for a free night at their hotel in exchange for YouTube videos and dedicated Instagram stories. This led to a much-publicised back and forth between the vlogger, Elle Darby, and the owners of the cafe.

But while social media spats might be one thing, flippant comments about a very serious rape trail are clearly another. The post received heavy condemnation, with figures such as director Lenny Abrahamson and former Miss Ireland Holly Carpenter calling them out.
