"Die Branche wiederum setzt seitdem zunehmend auf ungelernte Kräfte" - my point exactly. I've worked in that industry for 30 years. I'm a trained restaurant professional (Restaurantfachmann). I have certs coming out my butt and I've spent almost 20k over the years on my cocktail certifications. Then you open a "cocktail bar" and offer me €13/h to manage your bar for you and build up your cocktail business?

Yeah, no.
