Man. A restaurant is cooking for groups of 12-15 people at least 5-6 times per 5 hour service plus a whole dining room on top of that. And it's a race.
And you might be Swedish, but the "you should open a restaurant, friend" thing is time tested and an international language. We got tons of people here in America who have an innocent friend named Tim or something, they don't actually cook food for themselves, but they over invest in their weekend hobby, the guy might wear a shiny rayon Nike defensive coordinator's outfit while making some ribs for his friends.... friends who get into his head and convince him to part with like $300-800k of his money to make ribs for people who are not his friends. His wife instantly comes on board to decorate everything in shiplap and reclaimed wood.
The Lusitania moment comes in like 6-9 months when his wife gets bored of looking at her creation realizing nothing will change and the ship is afloat, her job is done, she is tired of her BBQ and booze restaurant and wants to eat something else and never comes back. Tim is suddently left with a half dozen 18 year old girls 12 hours a day, in a reclaimed wooden ship full of alcohol, and lots of meat, plus pirates fresh from prison to add to the atmosphere.
True story. That was my first restaurant job. I put X number of years into cooking after that (I had fun on my side) and got a Bib Gourmand 10,000 miles away from there. I'm also done with that though.
I heard Tim died not long after I left, he would have been in his 50's, his daughter in her 20's and I heard she got married, wife long gone before that with half his shit. It was up to someone to go take a wheeled rubbermaid into the office everyday and clear all the beer bottles, 24 bottles might be a Tuesday at 4pm. There's thousands of Tims in the USA, it's such a fucked up pseudo macho culture like football because it always somehow devolves to this sort of thing and hobby food (aka easy result foods for complete amateurs like BBQ) is always catalyst to this. Actually it's just BBQ. Like a shitty porthole for people who think they can cook but can't
