I had lots of fun discussions with both Israeli and US acquaintances about the fact that 'Business Administration' (as in, 'front desk & more') is something you have to learn in Germany (usually 3 years, apprenticeship split between working and learning at a school). These people usually said 'WTF? So, I know Word, Excel and can communicate quite decently - that's all it would take to get a job like that here'.
Expectations matter and are - to make matters more complicated - often heavily influenced by culture as well.
(You wouldn't be able to tell that I care about a barber that knows what he's doing, tbh. My wife claims I fail selecting the correct shop anyway, whatever I try. But I do support the 'please prove that you have a basic understanding of what you are doing' system)
Probably previously the onus was on the owner to avoid hiring underage girls. But a couple scandals later, the government responded by requiring licensing.
