Can you give some examples? I live in Europe and have never experienced that in my country suddenly everything stops for 2 weeks in the middle of the summer.
Citation needed. Germans do not quit working for 2 weeks in the summer. Where did you get that from? What German companies shut down for 2 weeks in the summer of 2019?
There's even a word for it. Google Betriebsurlaub.
I get that from working with and for German, Austrian and Dutch companies in Germany, Austria and the Netherlands. It's nigh on impossible to get anything done in August around here.
This doesn't apply to things like resorts and restaurants, for obvious reasons, though if that's what you're thinking of.
Yeah, your first comment made it sound to me like the country shuts down (grocery stores, home improvement stores, furnite stores, banks, offices, government agencies, taxis, ...) ;-)
