Eh, i would love to see a chaplain, but definetely not a chef.
Literally, cooking is one of the only things that keeps researchers and MTs distracted other then their own useless jobs that can usually be done 5 minutes in the round, then it's pretty much over.
Researchers barely even bother getting xeno eggs anymore because it just became a boring gimmick. MTs without nothing to do will just wreck havoc and chaos on the Almayer and steal Jones and the CO's booze, or some low roleplay shenanigans. I definetely would not like to have a chef as an official role when we literally have other people already performing this.
If you're hungry, eat MREs.
