I don't think I'll ever understand the human Christmas. You silly apes celebrate something that has caused so much strife through the years and doesn't even make logical sense. On top of that, there's no evidence that the event in question occurred on the 25th of December at all- it was named that way to coincide with the previous holiday of Saturnalia.
Yet the person running this horrid establishment seems to have an obsession with the "holidays". I just had a strange spectral image of a child come up to me saying it was the "Ghost of Christmas Past" and that they had to show me the "error of my ways" and now it's chasing me around the city.
