Having grown up in the northern hemisphere I have a particular mental image of Father Christmas/Santa Claus/Saint Nick/whatever. It involves a lot of clothing, topped with a lined robe. Y’know, typical cold weather gear.
In the southern hemisphere, do you get the same? If so, how come the poor guys cosplaying as him don’t overheat?
There’s no functional difference, we just use both terms. It’s a bit arbitrary, but generally once a mall is a mall we stick with that and vice versa. E.g. “Westfield St Lukes” is known as “St Lukes mall” colloquially by pretty much everyone.
