That would be interesting, but I suspect that transporting your dishes there and returning to pick them up would be more work than just loading them into a dishwasher. Unless the service were quite close by. Which reminds me, wasn’t room service once a perk you could get in some apartment buildings? You don’t often find dumbwaiters in apartment buildings any more, for example. I would pay for that if it were available.
