Preamble: I'm rated as an executive chef(my last 3 positions before leaving the industry), and I had worked for over 17 years in hospitality (from apprentice chef, to manager and executive chef - I also spent 4 years traveling to different restaurants to try and save them from foreclosure).
"That chicken is a confit (with duck fat, aka $$), then served with a stock/stew that takes days (of labor dollars) to prepare, plus cost of employees to serve"
I sympathised with the author until this point. No it doesn't take days in the way the author points it out, it takes minutes with a time to follow. (Eg you don't have to actually do anything after you prepare and set it). That's akin to saying a good jam or beer takes months - yes in pure time, but it doesn't take staff time(and $$ as the author said).
As for the hours? The author is correct, hospitality is a slug fest, there is no doubt about that.
What I take from this article? An unexperienced person tried to build a new business in an industry that didn't have the experience in.
Would you try to start a software business, a cloud storage or a trucking business without experience? No it would be foolhardy, and that's the biggest problem with hospitality.
Frankly if you're not a chef - dont purchase a restaurant. Anyone can cook one decent meal, now try doing 100 a day while managing costs and staffing. (That's just the basics, there are hundreds of things you need to do just to begin).
At the end of the day, I sympathise with the author, I have seen (and tried to help), a lot of people in that situation, but you cannot just jump into hospitality with money and assume that it will work.
