Call-centers
A Call-center is often an easy place to find a quick job when you are coming in a new city in a new country where you do not speak the language.
In Europe the call-center industry is not as big as in the United States or India but it is a very big industry, with many available jobs for expats or travelers.
Popular cities with a rather large international (where they emply people who speak other languages than the language of the country they live in) call-center base within Europe are Bratislava, Barcelona, Cork, Dublin, London and Amsterdam.
