This post is about suggestions regarding utilities that could be added to the kitchen/bar, and used by their respective employees.
As a chef, having condiment packets for deliveries (yes, I do use papersacks to deliver food) suits better than sending a ketchup bottle with 5 units in it. Made with plastic or from the condi-master perhaps, those packets could be transparent, opaque, and have stripe colours on them signalling the reagent colour in them, for example!
Another idea I had was making coffee serving trays (i don't know the name of 'em), why not? A cardboard or plastic tray with 4 coffee gaps in them, delivered to the customer. Sounds a nice idea to have as either a chef or a bartender, in my opinion. Better with labels on the coffee cups! (already doable).
Finally, the chef could serve themselves with a coffee master when the bartender isn't there, it gives them that drip of being a 'breakfast restaurant'. Another thing I thought was giving the chef hydro access by default when there's no gardener roundstart, but I do think that's exploitable, though we must agree it's a pain to rely on hydroponics for a way wider variety of food serving and not have access to it.
