Long story short, I educated him on how to keep financial records and record every single penny that comes in and goes out of his business. I also made him understand how this can help him cut losses and make more profit.
The things you pointed out are not peculiar to your friend alone in such small scale businesses. Most owners of such businesses don't see it as something that they can turn into a big business venture but they only see it as an end in itself, like a means to only feed, go with the girls and to sustain just immediate hunger and funfair.
They don't see it as a business that they can bestow to heirs and for that one of the challenges to it is they don't believe they have a future in the business. They don't see it as SME and they don't think about the future but to consider it as a time to hold on to pending when bigger employment job will come then they will fold it up and abandon it thereby killing the circle of SME growth that are suppose to be a good engineering to the economy.
Such barbing saloon business is suppose to be handled properly because they are part of small businesses and the government is interested in them. A more wiser business person on it can write proposals to government and may get access to loan for expansion and advertise the business online then you see more customers.
The buttom line is your friend is not seeing what he has found his hand to be doing as a business, he doesn't consider a future with it but looking for a white collar job.
