I was a Christmas elf in a grotto made of a large shed in an outdoor shopping centre. Had to wear three layers of clothes to stay warm. Turns out being a Christmas elf involves a lot of being shouted at by angry parents when you tell them they're not allowed to take photos because you have to sell them one instead. Who knew.
(Technically I was also a cleaner a couple years before this for my aunt's cleaning company but elf is funnier)
