If the restaurant were to be successful in the future, what new challenges would the Belchers face?

Inspiration for this discussion comes from a comment by u/ohnoanotherputz from a past post of mine where I asked about changing the status quo.

In u/ohnoanotherputz's own words.

Honestly if the restaurant started actually being successful, and now Bob has all new troubles as he is unable to deal with success.

To which I replied.

That's not a bad idea. This way, Bob would still be struggling, but for different reasons.
