One of the wealthiest places in the city of Prague is Dejvice. Well, it’s clear enough why it’s so wealthy. „Dej“ is the imperative of „Dat“ which means „Give“. „Vice“ is the feminine form of „Vic“ which means „More“. So clearly the people living in Dejvice are in the position to demand whatever you’ve got, and more. This is another place to steer clear of since you’ll inevitably be confronted by Rolls Royce driving mendicants who will demand that you give them money.
