In Russia, in many shopping malls, especially the biggest ones, there is a playroom, where parents can leave their children. The children will play there and will be looked after by the playroom staff, allowing the parent to do shopping. Of course this is for a relatively small fee (like €5-10 per hour).
A year ago I was in Germany in Munich, and I saw nothing of that kind; now I am in Berlin and apparently there is nothing like this too. Do such playrooms not exist indeed in Germany, or I just did not happen to find them? If they are really uncommon, is the situation the same in the rest of Europe?
