Serving at a Christmas party is a weird experience. You get to witness people who usually interact only in a strictly professional sense get together and destroy a venue in a way that resembles a 21st kegger.
Individuals who’s only interaction before was to nod at each other in the halls are now downing tequila shots and dancing and sucking face in ways that make anyone watching their display really uncomfortable.
It is this shift in behaviour that makes corporate Christmas parties interesting as a social study – as normal people devolve into slavering amoral husks who only feel the need to consume.
Like zombies. Christmas zombies.
