Just a note - my issue was from the perspective of simply visiting a restaurant, not owning it. So for all the fixes where you own the venue and can manage shifts, training etc that is helpful - but if you are playing the sim that is the customer you can't control any of that. So to me this isn't a management thing, where my customers weren't getting served, it's a gameplay issue. (I don't mean the info about managing isn't good, it is! hehe Just pointing out that there are really two different issues there.) I hope to play tonight some more and see what else I can find out about the issue. I mean I feel for me it is resolved - just pick a different table :D but I'd like to "permanently" resolve it.
