Interestingly, and it's something I don't recall seeing a good explanation for, most services tend to be offered precisely at the same time majority of people are working - thus making them unavailable (or barely available) to the working population. See e.g. barbers, banks, etc.
In a mostly-synchronous society, “standard” working hours become somewhat desirable. Working 9-5ish typically maximises opportunities to see friends and family, and for parents it means they get to take advantage of free government-provided childcare (aka schools).
Plenty of places are open outside those hours, but they tend to be shops and services provided by relatively low status workers. Higher-status service workers (dentists, bankers, ...) generally seem to do better at resisting “unsociable” hours.
It’s an annoying situation, but can’t see it drastically improving without a widespread move away from synchrony.
It looks as a feature of culture. When there is a demand, no legal obstructions and cultural acceptance, then barbers, banks, shops work late into evening.
