Apparently, the Sunday rule, which requires most businesses to be closed on Sundays in Germany with the exception of cafe’s and restaurants has apparently been expanded to the internet.
No kidding, here is proof:
This website is for American service people living in Germany near the Spangdahlem air force base. It is an American classifieds website for Americans to buy, sell and trade stuff. Yes, Spangdahlem is absolutely in Germany, but this is the internet and the site is run by AMERICANS. I think I’ve seen it all now.
