Always enjoy playing a Chef or Bartender. However, I wondered if Dishwashers could be implemented easily. You have glasses that you can wipe with a damp rag as a bartender, but it's only for roleplay purposes. The glasses themselves don't ever get dirty. It'd be cool if after someone used the glass and gave it back to you it would be a "Dirty Glass" and you'd have to clean it. Whether that be with a "Dishwasher" or just some soap, or the damp rag.
Same thing with being a Chef. If someone ate off a plate and handed it back to you. It could be a "Dirty Plate" and you'd have to clean it in the sink or with soap. Or put it in a Dishwasher. If you reused the dirty plate again maybe that person get's sick.
I know this is probably hard to implement, but I figured I'd see what others think about an idea like this.
