In many places if you run a (small) business _well_ that does craft stuff like plumbing, electricity and similar, you're going to have people lining up for your services to no end.

I don't know why that is. But I assume that the combination of excellent trade/craftsmanship and organizational skills is very attractive.

I always hear the same story from my friends who have been working in small service businesses, whether they are gardeners, carpenters, electricians or cleaners etc:

When it's bad (fairly typical) it's the boss being stretched too thin between too many responsibilities, or its a person that has no clue about the actual trade. They are the both the bottleneck for solutions and the cause of compounding issues.

It ends up in overworked, stressed workers, missed deadlines and mistakes that snowball into more such problems.

A trade/service business that is run well, treats their workers well (which is their major asset) and does good work can charge more and will never run out of work. It seems there is no simple formula for this so you end up with a lot of what you describe above.
