https://github.com/goonstation/goonstation/pull/124

Main points of disscussion on the Discord have been that :

pros
encouraged interaction with catering
provide catering with a purpose
higher exposure to food buffs
might encourage "food nerdery"


cons
forced interacion with catering
another incentive for people to break into departments because they can do it better
useless busywork every 30 mins
if not handled well can be very annoying
could negatively affect sec/antag rounds
